I should have been the 4th APUGer on the trip. However, I drove about 1/2 mile up the aforementioned road and turned back. Made the best of it, however, and drove over to Cloudland Canyon, a spectacular spot in an area full of spectacular spots.
Gary, I work with a guy named Ed Nicholas. He's head of the local cave rescue squad, and a Fellow of the NSS. He'll be excited to hear that you ran into Allen Padgett; they're old friends, and we sell "On Rope" in our shop.
