Well, I went skydiving today with two co-workers. Skydiving is one of those things that I always sort of assumed I would never do (I mean why would somebody jump out of a perfectly good airplane?).
It was actually pretty fun. There's a lot of waiting involved, and you have to sign several pages of "if you fall and break your leg, don't come running to us with legal documents." After that, you wait around a while. There was a short instructional video, narrated by some guy with a comically long beard, that was about 50% "why you shouldn't sue us" and about 50% "hey, come jump out of this airplane using our patented and totally safe harness; don't worry about any of that other stuff I just said."
We did tandem jumps, which was nice for the first time because instead of having parachutes strapped to our backs, we had trained professionals strapped to our backs (the trained professionals had parachutes on their backs). It was really fun; everyone there was very laid back and seemed to enjoy what they were doing. The worst part was the plane ride up, which was very uncomfortable. The freefall portion was really cool; it was very scary at first, because my brain kept telling telling me "you were just kicked off an airplane 15,300 feet off the ground, and now you're falling toward it at 120mph." Once you remind your brain about the trained professional and the parachute, it's an extremely cool feeling. The harness assembly was bulky, awkward, and uncomfortable, but it did its job quite well and meant that we didn't have to take any sort of classes beforehand. Landing was also relatively easy, though presumably that's a dangerous part. The people not doing tandem jumps were doing some scary looking acrobatics and coming in for pretty hard landings, but they were nice to us first-timers (thanks!).
Overall, it was totally worth doing, and I would do it again any day. In fact, I might do it again at some point.
