Pros:
Some interesting holes, doesn't take too long to play (maybe an hour), good mix of right/left doglegs.
Cons:
Poorly maintained, terrible tee-pads (uneven, rutted, and too short), overgrowth June-September, a few overly difficult holes (#3-5, for example), many tee/tee-pad placements don't seem to make much sense, signs are no help at all, front six holes are difficult to locate, hidden behind parking lot/road.
Other Thoughts:
It's frustrating to play a course like JSC because it could be so much better if it were well-maintained. It's kind of like playing an ancient course that hasn't been touched for years.
