Personally, anything that has to do with going fast and heights give me a rush. I LOVE rock climbing, downhill longboarding, cliff jumping...even being next to a cliff gives me a slight rush. Everytime I see a skyscraper, a cliff, a telephone antenna...I imediatly think about jumping off it (with a canopy of course). I also love white water kayaking. I'm in BSA, and I do these things a lot with my troop (not the jumping off buildings part...unfortunatly).
You?
