There were only five of us in the group which made it easy for Jack to take super good care of us on this 4-hour rappelling adventure. The hubbs and I were more than a little worried whether our +70 bodies could handle this experience. But the other 3 were under 40 and they were equally worried. Our worries were completely unnecessary. Jack was with us every step of the way. He was an excellent teacher and confidence builder. We took 7 rappels on different heights and with different surfaces to negotiate. Jack could tell us where to put each foot to make it easy. Our first rappel was actually the longest at 70' but it was also the easiest. Once we got that out of the way, our confidence grew immeasurably. None of us were athletes and we all did it just fine. Plus, the slot canyon is absolutely gorgeous. Experience of a lifetime!
