Technical trail that features the infamous Troll Bridge: a log-ride that takes you over a pond. If you fall in, you're getting wet If you choose not to attempt it, you can bail out before-hand onto Once Upon A Time via The Lorax. There is also an easier skinny, a raised ladder bridge with a turn, and plenty of obstacles to keep you busy.

       It appears that the trail route had been shortened, still a fun, technical ride. The troll bridge was overgrown earlier this year, but is now visible and ready to ride.
