Actually, there are some people who travel in a mode not unlike homelessness. I did a few hitchhiking tours around Europe, back before I'd heard of couchsurfing and hospitality club, where I would hitchhike and camp out in cities (an urban camper, as the parent says), cooking food on a Primus gas stove, washing up at gas stations and occasionally scoring a shower at someone's house. I never actually dumpster dove, but with the right attitude and weather, guerrilla camping can feel strangely liberating, especially if you do it in Scandinavia, where it's perfectly legal.
