Cliffs don't scare me at all, as long as I am at the bottom and no one is at the top to drop anything on me. The tent thing is scary to me because it lasts for so long. The people on the edge of the cliff can get away from it, and the ordeal is over.Skydiving looks like fun, and hang gliding looks like it would be even more fun. I went parasailing once. My wife and I were in Bali when we'd been married got about a year, possibly less. The currency had dropped and she paid a little over $100, I think, for a 24 hour bus ride to Bali, food included, maybe 3 nights at the hotel, and a couple of tours, and the trip back. The hotel was on the beach. It was a big hotel, so we did have to walk a bit. The waves came in like clockwork. I would have liked to just body surf every day, but my wife was sitting on the beach nervous the waves would eat me and not bring me back. Waves aren't her thing. One of the days, we went to another beach on the tour. They were offering parasailing for about $10 (in rupiah), but told the Indonesians they'd charge them $2. We negotiated for me to get to do it for $2. We both went parasailing. It was okay. It wasn't as scary as you might think up there, but other than the view, it's a bit boring. There weren't a lot of G's.. I was young and light and the straps dug into me a bit. That would be my concern with hang gliding, too. There is a mountain on the east coast of Oahu, Hawaii near Sealife Park where the wind comes in, and people can catch the wind and either hang glide in the currents or else parasail. They climb up part-way, catch the wind, and fly around in it. It does look like fun. I had a conversation about it with one of the men who'd been doing it and had a look at his equipment. But people who do that probably have to devote a lot of time to it just to learn how to get up there
