Pros:
Amenities. Picnic Shelter, reasonable amount of parking.
Beginner Friendly. If the course isn't too crowded, this would be a great place to learn the game to practice lines, approaches, and putts.
Local Scene. Local clubs have regular leagues and tournaments.
Tees. The short concrete pads are level and suit this course fine, typically not long enough for a full runup though.
Baskets. All existed and were in good shape.
Maintained in the winter. Locals keep the pads clear and a bucket of salt was provided at several tee pads.
Quaint little park only about a mile off the freeway.
Loops. Two 9 hole loops bring you back to the vehicle halfway through the round if you're on time constraints, otherwise you're never far from the vehicles anyway.
Cons:
Variety. Every hole seemed pretty much the same with a few exceptions: about 200 feet, avoid the trees scattered in the fairway.
There's also no use of water and very little elevation in the park, though the river is in view it is never a threat.
Length. Every hole was around 200 feet (varied from 120-300 or so), could be a good place for a single disc round (putter/midrange).
Signage. Some of the holes had signs, but most of them were missing or in very rough shape.
Navigation/Cramped. These are a single bullet point because the fact that there are several baskets and tee pads scattered about a very small park make it very hard to tell which tee pad is associated with which basket, and which tee pad I should walk to next. Improvement on the signage might help here (or reduce the number of holes in this size of an area).
The cramped quarters also result in crowding, I haven't experienced, but heard horror stories from locals of tournaments that fill the course to capacity, the holes are far too close together to have that many people playing this course.
No practice basket.
Other Thoughts:
A cool place to remember disc golf roots if you're into experiencing history first hand. Not really worth the stop for an intense challenge, but is a perfect place to learn the game and work on short technical lines through the trees, approaches and putts. I'd say yeah, make the drive off the freeway if passing by.
