I like the feeling of speed, especially free fall in a controlled environment, or anything else in a controlled environment. Uncontrolled speed (like flying out of a car or falling off a building) would not be a very fun experience, because I know the sudden stop is inevitable.
I'd love to go skydiving some day. I'm getting LASIK in a month from now. I will wait a year for full recovery and seriously look into it. Doing it with glasses would kinda suck, especially if there's moisture in the air, or if I'd have to take them off. I went on a ~160' drop swing ride at Canada's Wonderland but the ride required to take off glasses. I may as well have been going on a regular swing, because I could not see a single thing anyway.
I rather be the one driving if I'm going very fast in a vehicle though. I also rather be alone if I want to go really fast. Whenever I take a 4wheeler or other toy out at camp, I always go faster alone than if I have a passenger, and when I am a passenger, I don't really like going as fast as I go when I drive. Something about control, and possibly lack of faith.
