Whatever your feelings about homelessness, there is no argument that it is an important social issue. I suspect that most of us have never spoken to a homeless person, other than to perhaps utter a phrase while giving someone some spare change, a meal from a fast food joint, etc.; I know I never have.
I stumbled across Ronzig's Blog via his flickr gallery. I recommend visiting both. Clearly Ronzig is a very intelligent person, and his determination to champion the issues of homelessness is extremely moving.
