The other day I was hanging out at the Looking Glass Lounge with some pals, and made a trip to the downstairs bathroom, as people drinking beer are wont to do. In there, I noticed some graffiti scrawled onto the wall in big letters: FOIA. I think that might be the most DC graffiti ever.
And that's awesome. I doubt many other cities have folks who know what the Freedom of Information Act is, let alone care enough about it to write it in bathroom, then add to that the added step of having other people immediately recognize it -- what a town we live in.
(That said, Looking Glass is a good spot, don't graffiti their bathroom.)
