Rebuilding Place in the Urban Space is written by a historic preservation and urban revitalization advocate and consultant in Washington, DC. Fascinating stuff.
i learned of this blog through Frozen Tropics, one of my favorite blogs. Frozen Tropics concerns itself with Trinidad, sometimes Near North East ( SoFlo), and the economic strengthening of H street NE, one of the hoppin-est spots in the city.
also, it has great photos.
