Kauai - 24
So. My adventurous wife wanted to zipline. I have a deadly fear of heights, but I didn't want to go on this trip, come home, and say, "oh, wish I had done that". So sweated bullets for about three or four days, went with her and geared up. After nine ziplines, one about 1500 feet high, one 1200 feet long......yeah, I'd do it again!
