Spring Mountain Ski Area, Pennsylvania (December 2006)
As a surprise Christmas present for my parents, we delivered our gift via an indoor zip line. Leaving no chance for anyone to even think it over, we were already scheduled for the next morning to go do it.
The Spring Mountain Ski Area has a year round zip line canopy tour that integrates a full obstacle course with rope ladders, wire tightrope walks, wobbling bridges, and a final rappel back to earth at the end, all interspersed among multiple zip line runs. Fun guides and the interesting variety along the way made for a great outing. And everyone did great!
