Pros:
As of May 2009, this course has 18 baskets and 18 distinct holes, which really improves the course. Know this: the course is long (most holes >= 300 feet, with several significantly longer) and tends to play long with the wind, which is very often significant.
There are not very many birdie holes for recreational players (maybe 4 or so if you can't throw 300 feet). It's a difficult course cut out of some beautiful landscape. Great punishing rough. Snakes and who knows what in the heavy rough. Watch your shots.
There are a couple awesome holes with elevation (hole 1-- pictured-- is really bitchy; short and downhill, but plays to a green on a small hill. Birdieable but very easy to 4 or 5). Plenty of holes have baskets situated just up on a little bluff or on the edge of one, adding risk/reward to the game. Overall there is a good variety of holes on this course, though most of them are relatively open. You'll use quite a few different shots to play this course at even close to par. Hole 18 is a great finishing hole, playing 320' over the reservoir (water in there most of the year) or you can play it safe like a chump and try to get up and down for par.
Downloadable map from the course website will be helpful but not necessary; it's pretty easy to find your way around. There are a couple jerryrigged signs on the ground (arrows made of debris) to the next tees which are a nice touch.
The tee pads (about 2/3 of them are poured concrete as of this writing) are great, long, professional-style, with nice signage.
It's rough terrain, and not an easy course, but this is disc golf, not putt putt. You want to be punished when you throw it in the rough.
Leave the kids home for this one.
Lots of wildlife; I see roadrunners, lizards, hawks, rabbits, and more on a typical round. Hopefully no snakes, but you never know. It's the desert, y'all.
There's a water fountain just off of hole 18 which you'll want to use.
Cons:
The Titanic hole (800' or so) on the back 9 is boring, a disappointment, and not a good use of the landscape (other holes are all very nicely designed). Just open and wind and throwing long. Hopefully the designers will put in an alternate pin to the right so your upshot can play into the woods to add interest.
The course could use a few more technical holes in what woods there are for variety (there's not a lot of woods, but there's lots of scrub brush and mesquites; if you're used to golfing in the forest, this will be an interesting change; go up to Flagstaff instead).
Recreational players will find this to be a challenge. Heat is an issue in the summer. Bring lots of water.
During the monsoon season (July-August) 2008 much of the course flooded due to some problems with the water. That made the course... interesting... but probably unplayable for all but the most hardcore players. Word is the Army COE is on it so it shouldn't happen in the future, though I haven't been up there to play yet in the monsoon this year.
Other Thoughts:
This is certainly the best course I've played in low-elevation Arizona. Well-designed, well-maintained, and lots of fun. Recreational players try Groves or Santa Cruz. Anyone looking for a longer, nastier course with some awesome desert scenery and wildlife will like this a lot.
