I skydived (skydove?) for the first time yesterday. The rush when I just walked off the airplane into nothing and realized what gravitational acceleration actually meant was incredible. The experience would have been even sweeter had I actually pulled the cord myself and steered some more.
Still, jumping off a propeller plane with a 220-lb hungarian man strapped to your back and realizing all you have is 12000 feet of thin air between you and the ground is quite exhilarating. I would definitely do it again, if only to prepare myself to do a solo.
