I guess I'm kind of taking up the job right now of selling stuff online. I don't know how much that'll get me but a guy I know does that for his whole income and he seems like he can at least take care of himself. He knew a guy that walked (not biked) from New York to California.
If I can get there with my stuff and not die in the process, I think that's the minimum I'm going for.

I'm gonna check out some thrift stores and see if I don't get lucky.
