-Good lines, definately a risks vs. rewards course.
-Can play the 'Quick 9' with holes 1-4 and 14-18.
-DJ's usually out with a good selection at decent prices if you lose a disc.
-Easy to navigate. (Mostly)

-Bugs. Lots.
-Graffiti and trash. Lots.
-Usually have to end up skipping two or three holes to get around groups of 4 to 8 who seem to only barely realize they're in the woods, let alone playing disc golf. Expect no courtesy.
-Usually have to skip two to three holes due to flooding.
-Easy to lose discs, even on the best of days there are a thousand little niches, a pond and a river within most drives.

I'll admit some bias on this review. It was the first course I ever played, and one I've played dozens of times. Each time I seem to be sorely disappointed in new ways. Mostly, people at GW are of the variety that give disc a bad reputation, and there are masses of them. If you aim to play it, catch it early in the morning before the idiots overrun the place, when it hasn't rained for a few weeks, and bring bug spray.
