James,
I like this fellow and have been waiting to see what reactions there would be.
The photograph is interesting, not the usual bum that one would want to pass by as fast as possible without engaging. I bet he has a lot of good stories and is worth hearing out. There's a certain breed of folk who like the freedom of collecting and recycling but not having to deal with the rest of the burdens of society. They hunt for paper, cans and other materials and so do everyone good.
He seems to be amongst the more civilized and interesting of such hardy folk who managed to survive in this lifestyle.
