I brought a group of Varsity Scouts for the zipline tour, and they all found it one of the highlights of their "High Adventure" trip. Our guides James and Preston were superb, from the corny (but new) jokes, to the exposition of the geology and ecology of the region. The price is steep, probably mostly to pay the liability lawyers and insurers; but we felt safe, and the most hesitant at first was soon the first to snap onto the next line across the picturesque small canyon. Given the chance, we'll be back to try the other options, and hoping the new loooonger zip line is installed by then!
