This is off-topic, but I'll bite: BASE jumpers do this. They do it in Yosemite, even though it is illegal -- they do it early in the morning so fewer people will see, and they can quickly hide/pack up their gear and walk out. I once talked to a guy who was on Half Dome early one morning who watched a guy do it.
