So I ran across this while reading up on skeleton for the Olympics. It is called airboarding which is basically hauling *** down the slopes head first on a small inflatable raft looking thing. Some say it is ghey, but many say Miatas are ghey too so we should be able to relate here
An example for the speed junkies. 133 kph ~ 83 mph.
Cool or ghey? Looks like fun to me. Plus it puts the rider in the ***-up position for easier access.
