Yes, I was quite the source of much laughter that day. I don't have a fear of heights. I'm one to lean over the barriers at the Grand Canyon as far as possible, LOL. I have to admit that I was a bit apprehensive on the first zip. After doing the first one, I couldn't wait to do more. Nobody in the group seemed afraid. I believe there are things you can do w/ your legs to slow you a bit. Mostly it's a weight thing though. I know I tried to make myself go faster by pulling my legs in (knees to chest) to consolidate my weight. It really is one of the most fun things I've ever done. Now I weigh even less so I'd probably have to cozy up w/ one of the guides to do the ziplines or I'd be hanging way out of reach. When will you be in JA to do this?
