The Vanity Ballroom in Detroit in the summer of 2012.
The first time I saw the ballroom in 2007, I barely had time to look around before being chased out by someone who claimed to live downstairs (the bottom floor was once occupied by stores and is now in a pretty destroyed condition). At that time there was hardly any graffiti and the wood floor was still up for a few dances. Since the stairway was busted wide open earlier this year, the building is going the way of so many other architectural gems in this city. For reference, the Detroit News recently published a nice historic photo of the space as part of its essay Detroit Dances Through Time.
