What I did on my summer vacation. Two days before my Ironman I risked life and limb going down the old bobsled course on a wheeled bobsled in Lake Placid. At half speed it was amazing. I cannot imagine going faster. Wait, yes I can.
For a look at a bobsled crash go to NBCOlympics.com, click on "video," then find "Bobsled," then "4 Man," and find the one of Todd Hayes crashing. Watching the two guys spit out the back of the sled is almost commical.
