Have not had time to figure out yet what Preservation Detroit does? Well now there is a video that can help you with that. You may have heard that this organization recently changed it's name from Preservation Wayne. [note to Gilbert re-branders the conspicuous absence of a gimmick like 2.0 or spelling it Pre$erv@tion] The video gives you the chance to ogle the David Mackenzie house, the most excellent (obviously historic) home of Preservation Detroit [pictured above], where the founder of Wayne State once lived. Students saved the home from demo in the 70s when the city wanted to put in a sewer line.
