has anyone ever made or had the crazy idea to have an outragiously high hanging hammock?...just because?

i was thinking it would be cool to have two pulleys really high (like 50ft) on two trees...you would get in, and then start to pull the two ropes and rais up up the 50 feet. tie off the ropes somehow and sleep overlooking everything...

yes i am very bored, but i thought it would be cool...near impossible to do, and completely pointless...but i would be neat!
