The two dead ends we hit behind the tennis courts were kind of annoying. We're talking about riding and the trail just stops and we had to turn around. The other dead end we hit was in that "mud bog" area so that entire trail was a nightmare anyway. We had no problems finding our way back into the woods when we ended up on the paths, I remember all of those entrances.
The only other section I was disappointed with was that you couldn't cross the log and come out the other side of the dam anymore.... I used to love the ride back there.
Top it off with eric face planting off one of the man-made obstacles and it was a pretty rough day
