This is wonderful, you get a guide to give you the background, history and fun facts about the graffiti you see. This is especially excellent if you are a photographer and have a collection of graff flicks you love to add to.
Get busy with your Flickr account and take a tour!
Based out of NYC this is a good way to get to know the spots!
Take tours of SOHO and The Lower East Side of Manhattan amongst others.
