My wife and I spent Labor Day afternoon on the Treetop Obstacle Course at Arbortrek Canopy Adventures in Jeffersonville, Vermont. It was arduous, difficult, and enormously fun… right up until my upper body strength gave completely out on the last, extreme-difficult obstacle and I had to be rescued by the staff. (Rescued = rappelled to the ground) We’ll be back. Highly recommended. The staff were ultra-professional and very attentive to participant questions and needs.
