What an excellent article. You've really outdone yourself this time, Aaron. It's especially ironic when you consider that Philadelphia has an estimated over 26,000 abandoned houses that Mayor Street could have done a whole lot more with, in his so-called "Neighborhood Transformation Initiative" (this from a man who started his political career championing squatters' rights with ACORN.) Another good resource for information is http://www.thesimpleway.org/housing/

Peace.
