I've mentioned here and there how the Palmer Park neighborhood used to be the old gay 'hood back in the 70's and 80's (and better yet, readers have chimed in with additional info). Recently I came across this flickr photoset with pictures of the buildings in that area.
There are some really sensational buildings in that McNichols/Woodward area. If you can't make the drive through yourself - and with summer in full bloom there's no better time - then this will be a nice substitute.
