Going to London soon? Check out the Disappearing London section of London Footprints, where you'll find some interesting things to look for on the London landscape. The official Disappearing London site is fun as well. Be sure to watch the clip of Suggs (the lead singer of Madness) and Stephen Fry taking snuff at the tobacconist. I didn't realize you could even buy the stuff anymore.
What would you nominate for Disappearing Boston?
