When I ran away at 15, the only means of transportation was hitchhiking. I traveled across county twice, and up and down the east coast several times. I wouldnt trade those experiences for the world either, even tho at the time it sucked.
This was back in the early to late 70's, a much nicer time. I wouldnt advise anyone doing it now.
Hows about you? Ever do long trips with your thumb? Any good stories?
