Pros:
Sinissippi Park is a very nice public park. The concrete tees are in good condition, and the signage is adequate. Nice baskets are featured on all of the holes. The first five or so holes are great. Elevation changes, large trees, and water hazards make the first handful of holes very fun and challenging to play.
Cons:
This is a very busy park. It has a number of shelters, softball fields, and walking trails that have a high volume of use. This takes away from the "scenery" that makes disc golf fun for me. After the first five or so holes, they become very typical public park disc golf holes. Not extermely challenging or scenic.
Other Thoughts:
I lived in Sterling for about two years, and played this course multiple times, as it is the only quality course anywhere around. I can't remember a time that our group didn't have to wait to throw for people using the park for other activities. This becomes frusterating, as it makes your round take much longer than it should. The layout could be much better, as shelters, softball fields and walking trails come into play on many of the holes.
