Pros:
Signs are very nice, more than what I expect at a practice course and the rubber tee pads are a nice cheaper alternative to putting down concrete pads. Holes are laid out in a way that it would be very hard to lose a disc and there are few trees, long grass in your way. Though it sounds very open, it doesn't feel like you're just playing in a field.
Cons:
Four of the five holes are easy birdie holes and the longest is just over 300 ft. Would like a few more obstacles and one longer hole (400 ft at least), but it's a great start and a great practice course to get a few holes in at.
Other Thoughts:
I lived just across the street from this park for years and I can tell you it's very quiet when no softball, rugby, or soccer is going on. Would make for nice, peaceful practice time.
