Pros:
Two Rivers is a fairly open and beginner friendly course, that being said it can still be a challenging course even for more advanced players if you are really trying to go for it on every shot not to mention there always seems to be some kind of wind. Most holes have multiple lines for reaching each pin placement so no matter your playing style you have a good chance at reaching the basket. Both a pro and con it is a fairly short course with only a few long (350+) holes. I consider this more of a training course that is great for working on touch shots, new discs or learning to play in the wind.
Cons:
This is a multi-use park so you have to be careful and watch for other park visitors, mainly on the front half of the course due to the bike/walking path. Inconsistent tee pads can be annoying at times. Some are a little dangerous I've tripped or lost my footing on tee pads for hole 4, 15 and 17, but I've heard they will be doing some work on them in the coming months. Signs are poor not showing where the next tee pad is and even missing some of the pin placements, best to play your first round or two with someone that has played there before. Finding the first hole can be interesting if it's your first time, it's back where you entered the park but there is no parking anywhere near the tee for hole one. Moles seem to be prevalent here as well so you have to watch your footing at times when walking.
Other Thoughts:
Not my favorite but I play here often since it gives you more freedom to test out different shots and work in your wind practice. It would be nicer if there were a few more long holes to work on your distance throws in the open field. I will give a brief overview of the holes of the course to give you an idea of what you'll be getting into. I must mention I am a right handed backhand player, so any shot suggestions are given with that in mind unless otherwise noted.
Hole one is a fairly simply hole the pin is a good ways below you, straight ahead behind a large tree. The low hanging branches on the right side make this a nice touch shot coming low under them, most pros I've seen will try a high hyzer and attempt to crash through the tree with varied success. The left side of the tree is more open making it a bit more of a side-arm or lefty friendly hole. This is a possible ace (hole in one) hole but not guaranteed, I have clipped the basket with a side-arm and low skip shot.
Hole two, a fairly straight forward shot with the basket straight ahead, an OB (out of bounds) road 15-20 feet past it and a tree on the right side. There is also a rather large tree just a little ways off whose branches now are low hanging and blocking the hyzer line. This is the first true ace hole, though you can risk going OB if you throw a little too high. A nice slow anhyzer or straight shot is the preferred route, once again this is a lefty/side-arm friendly hole.
Hole three is the first difficult shot if it is in one of the long positions. The short position is straight ahead and easy to reach, but the pin is rarely in this location. On this Hole you are throwing uphill towards the tree line, a blind shot since you can't see the gap you are trying to reach and there is almost always wind here to affect your disc. The gap is almost straight ahead but only roughly 10-15 feet wide with a couple of trees in the dead center, it is easy to block yourself out off the tee if you get a little too far right or left. There is a high window on the right about 30 feet from the main gap if you happen to pull your shot right off the tee. This hole definitely forces you to place your shots well.
Hole four forces you to throw through a twenty foot gap forty feet away, not a difficult shot but the fact that you are throwing slightly up hill and the ground levels out then goes downhill means you have to place your shot well again. The first pin position is a fairly simple hyzer through the gap and turning left, there tends to be a headwind you don't feel off the tee here that can mess with your disc a little. The second pin placement is nearly straight ahead a little off to the right, the uphill then downhill factor coupled with the headwind can make this a challenging shot at times. Both pin placements force you to throw blind shots.
Hole five is fairly straight forward, a downhill shot with the ground sloping downhill right to left. The pin is slightly off to the right with a few trees to shape your shot around. Preferred route is throwing straight at it avoiding the low ceiling, but there is also an option of throwing a stall shot through a right gap and letting your disc fade towards the basket. A touch shot but this is the second possible ace hole.
Hole six is straight ahead on a slight incline, fairly open allowing a wide range of shots. Still this requires placement if you can't reach the pin in one shot because it is possible to have your disc roll away if you miss your upshot.
Hole seven shares a tee pad with hole nine, another nice touch shot here on either pin placement. If the pin is in the first placement it is straight down the path and a little to the right, with trees on the left and right creating a 15-20 foot gap about halfway to the pin and a low ceiling. The ground falls away to the right so getting your disc to settle and not roll away is key. The second pin placement is down the path and to the left near the paved path (OB). You can take the same gap as in the first pin placement here just making sure to end up left but not going over the paved path and out of bounds. The second line is to go to the left of the tree just left of the path, great shot for lefty/side-arms or if you have nice anhyzer shot. Even if you do make a good shot off the tee you must be careful not to push too hard on your putt and end up OB on the path beyond the pin.
Hole eight is slightly uphill straight ahead with the ground sloping downhill to the left. A fairly straight forward shot, what makes it interesting is the wind can really affect your disc here being on top of the hill. I have played here a lot and the wind can come from just about any direction.
Hole nine is straight ahead down the path or possibly to the left just off the path but it rarely changes position. This is another touch shot but is a possible ace if you can throw long and straight. The main problem here is there is a major slope going right to left downhill the entire length of the fairway making this a very interesting shot for right hand backhand throwers. If your disc hyzers out at the end you can be looking at a very difficult putt with the basket at a considerably higher elevation. Trees down the left side can block you out if your shot isn't perfectly on line here. There is another option of taking a wide hyzer to the right following the slope of the hill around a tree if you can place it well and not skip to far, this is my preferred shot here.
Hole ten has two placements, the first is behind a tree straight ahead . The ground slopes downhill right to left again, that being said the preferred line is a hyzer crashing in at the basket near the tree. The second placement is in the flat of the valley with a large tree on the left forcing you to shape your shot. The preferred shot here is throwing straight out barely missing the tree on the left, the only downside is the distance you have to get with this is difficult unless you have some real power. The wind can affect your shot hear as well. Another option is if you have a good tomahawk shot you can flex around the tree. The third option is throwing a wide anhyzer around the tree to the left and letting it work back towards the basket, this is the route I have seen a few pros take.
Hole eleven is downhill straight ahead behind a large tree. This is another ace hole if you can shape your shot around the tree.
Hole twelve is possibly the longest hole on the course depending on the pin placement. Trees on the left, right and straight ahead will make you shape your shot somewhat. The pin placements are focused around the large tree about 300ft away, being left, right or about 150ft behind. This is a great hole to work on your flex shot or flip up hyzer. The wind here swirls around and can affect your disc tremendously; I have experienced headwinds, crosswinds and tailwinds here making this a good hole to practice getting distance in the different types of wind.
Hole thirteen can be touchy depending on the pin placement. The ground falls away left and right off the main path down the center. The first pin placement is down the path just off to the right behind a large tree, choosing how to deal with the tree makes this a very touchy shot. I consider this placement more lefty or side-arm friendly. The second placement is straight ahead beyond the trees by about 50-75ft and a good 10-15 higher in elevation. The trees create a low ceiling that force you to throw long and straight and you are still left with a difficult putt uphill. If you have the power it is possible to take the trees out of play going with a high hyzer up and over them, but that can bring the wind into play.
Hole fourteen you are throwing over a valley at the pin in one of two positions on the opposite hillside, the wind tends to push you left here towards the woods/bushes so be sure to put your shot out wide enough. The first pin placement is wide open, the second is slightly behind a tree. There is a possibility of going too far and going over the fence if the wind takes your disc, but not a consideration for most.
Hole fifteen focuses around an uphill shot around a large cedar tree directly ahead and a few other trees beyond. There are two pin placements, the first on the right is an easy soft hyzer. The second placement is directly ahead past the cedar tree, the hyzer shot here is difficult being uphill with the trees beyond the cedar creating a low ceiling. There is a fence running down the left side of the fairway that is possible to throw a large anhyzer for those that have the shot, just make sure you force it over enough to keep it in the fairway. This is another lefty/side-arm friendly position.
Hole sixteen has two placements with the ground sloping downhill to a great degree left to right with trees creating a low ceiling. Placement one is straight ahead behind a tree, this is a touchy shot with all the trees around and low ceiling. The second placement is straight and right almost at the bottom of the hill below the second far tree on the right. A nice semi-flat anhyzer or trying to crash through the tree on the right near the basket are about the only two options you have here. There tends to be a tailwind or slight crosswind here so choosing the right disc to reach the basket is key.
Hole seventeen is slightly uphill with a mando on the tree straight ahead and slightly to the right (you must be left of the tree with your shot). The pin is straight ahead and slightly off to the right with a wide gap to throw through and a large tree between you and the basket. An anhyzer is the best option here just make sure to clear the mando being uphill this can be a little touchy, yet another lefty/side-arm friendly hole.
Hole eighteen is straight ahead across a slight valley with an OB road (and fence) running down the left side of the fairway. The tree the tee pad is under can sometimes create a low ceiling if it hasn't been trimmed. There are two pin placements, the short one is straight ahead reachable with just about any shot you want to go at it with and a possible ace hole. The second is long with the basket situated amongst three guardian trees. The interesting factor here is the wind, sometimes there is a crosswind from right to left that can push your disc OB. At other times there is a headwind that pushes your disc right and you can be in danger of hitting the playground area. Using the wind to your advantage here is key.
Well I hope this helps give you an idea of the course and what to expect, have fun.
