This got me thinking about affordable housing more broadly. For instance, where could I find a good, walkable neighborhood, anywhere in the country, that is within my price range? That got me started on my current project.
That said, this is a serious case of the pot calling the kettle black, considering I've roped veen into a multi-week project involving GIS data, Isochrones and the census bureau. I can't really get into it at the moment but the screenshots are impressive.
