Pros:
It's got 27 holes, (that's like nine more!) yet still has two different loops to accomidate 18 hole rounds. Flows very well for the most part. Very friendly for casuals to learn on as most holes don't have a lot in the way of obstacles. Varied pin positions on each hole give players different looks. Board 'B' tees have been recently installed to give users more options. Elevation holes on the last nine are fun, even if they're devoid of obstacles for the most part.
Cons:
Since the overgrowth at the only other course in town at Tierra Park can make it near unplayable during the summer, this is considered about the only place to go for casual players, so expect crowds on a nice afternoon. There are a few short holes that are purely Par 2, and make you want to say...that's it? Not much in the way of trees along most of the course. Maintainence along the creek has ruined Hole 17.
Other Thoughts:
After 20 years MRP is still a fun course for the majority of disc golfers, although advanced level players would probably state that it is starting to show its age. Even the long downhill 666' bomb isn't terribly difficult.
Don't have time for 27 holes? You have two options here to play 18. Start at Hole 1 and after Hole 13 cross the creek to Hole 23 and resume, or you can start on Hole 10 and play through 27. The latter arrangement is a tad more challenging. Hole 17 used to be a knothole tee where you had to put it through a tunnel of trees over the creek. Maintainence has cut all those trees down, so if you're going to play that hole, you might want to just opt to make your own tee along the sidewalk than use the one provided for more challenge.
Unless you want to deal with the thick foliage at Tierra, this is about the only course in town, and its not far off of I-80, although figuring the route to the parking lot can be tricky. Worth a stop if you're passing through. Just don't expect anything spectacular.
