When we got home from our trip I posted the photo on flickr with the tag "sign" and it has become my most popular photo by far. None of my cool neon sign photos or funky art shots or architecture shots come close. I guess everyone appreciates a good chuckle.
The waymarker Team TGF saw it and said there should be a category for unintentionally funny signs. I know that someone brought up the idea a long time ago, but it never went anywhere. It would be a great category though, and if I don't remember to bring it up in the forums and get it going, someone else do it. It would be a great companion to the "odd business combos" group. I found one of those in Evanston too - a combo fireworks store and liquor store originally called "Porter's Fireworks and Firewater."
