I've read previously that you can move up to 12 miles in any direction while falling if you aim for it. Over most of America this gives you ample opportunity to find a tree.<p>I've also read that you should come down in a sitting position on top of a tree. Haystacks seem like they would be too hard to spot until it's too late. A grain silo might be recognizable and have a thin enough roof to be helpful.<p>I suppose you could aim for the suburbs and hope someone has one of those obnoxiously large trampolines.
