Travel from place to place, meet people, get into adventures...

I've been thinking about that Pulp Fiction scene lately when Jules wanted to "walk the earth". Has anyone had the desire to just pack a bag and start walking the road/hitchhiking? I've been trying to walk the straight and narrow so I can get a good job, have a wife and kids and a house someday. No matter how hard I try it doesn't seem to work out well. I've always wondered what it would be like to "walk the earth".
