I've only picked up a little on them, because they haven't been covered much, but they're clearly part of the general anti-materialistic trend that winds through the last few decades. Part hippie, part hobo, part something you can't quite put your finger on. Here's an article I saved last winter:
http://www.nola.com/news/index.ssf/2011/01/those_who_died_in_warehouse_fi.htmlNationally, the culture of young travelers has not been well documented, making it difficult to answer basic questions such as how many young people follow the vagabond lifestyle and whether the phenomenon is new or simply the modern version of the old-time hobo with his belongings tied to a stick. . . .
In their view, taking over an abandoned building and using it for shelter is recycling, not trespassing. Hitching an unauthorized ride on a train is considered "green" because it doesn't use extra fuel. Why work a 9-to-5 job when the money goes to purchasing things you don't really need, the thinking goes.
Outsiders who have spent time in these circles say they are especially struck by the generosity they have witnessed. By that token, a traveling kid might beg for spare change, then not hesitate to split her take with a stranger who is also in need. . . .
Young travelers tend to be creative types -- talented musicians or writers -- who are rebelling against the expectations of mainstream society, she said.
