Pros:
For a seasonal, winter only course, it is a very good offering. While being mostly open, you do get a good variety. There are wide open long ripper holes, fairly tight tree lined holes (no pine tree tunnels necessarily), long and short wooded holes, uphill, downhill, across water, along water, and great left/right/straight balance.
While I don't remember the actual hole numbers because I played a while ago and we didn't start on #1 either, I'll try to describe some of the more unique holes. One hole you throw from up on a ridge under a canopy of pines and out through a tunnel of pines to a pin straight ahead below. I liked throwing this hole twice. Great straight ace run with a buzzz or putter. There is a somewhat long downhill bomber hole on one of the sledding hills. It could be quite a bit longer and really be spectacular, but it was good anyway. The next hole after that is across the creek so you do get some puckering going on, especially in the winter with bad footing and thin ice.
The balance and variety is really what pumps up the appeal of this course. You get to play up and down the sledding hills, along and across the creek, through and into/out of some gatherings of trees, and across the mainly flat parking lot areas with decently designed holes with a handful of trees that do some shot shaping. For a winter course, you're still forced to throw some 400'+ holes, and one of those is through a fair number of trees (I think it was over 400').
There are more than 18 holes.
Cons:
The course is mostly open.
Only one set of tees.
Not really any risky pin placements, or greens to think of.
Being a winter seasonal course, wind is a con. Because this course is wide open, winter wind is awful, and leads to looking for wind blasted shanked drives as well as cold bodies. I prefer closed up, tightly wooded winter time play, where the blanket of snow and tree blocked breezes provide an eerily silent and peaceful round.
I think the sleeves are permanent, and since most of this course plays across the ball golf course, the design does suffer a bit. What I mean is that I'm sure the parks department doesn't want a pin sleeve or ruts from a rubber mat tee area in the middle of a ball golf fairway, green, or tee box come summer. So the disc golf tees and pins are all located off the defined ball golf hole components. This holds back the design potential because some ball golf greens and tees would also make excellent disc golf tees and greens!
Other Thoughts:
The course has many components that really give a course the extra points in my course ratings - elevation, water hazards, balance, unique terrain, and more than 18 holes. But I don't think I can rate it any higher. It's only seasonal! It is also mostly open. I did enjoy playing, and given all the other course closures in the area I would play again next winter.
