Having worked in a Baltimore bar for a period of time I've constantly seen groups of people hopping from one bar to the next in the masses trying to drink at as many places as possible in an area.  But I recently came across a group through a friend that is planning a crawl of their own.  A cupcake crawl of DC.  Yes thats right cupcakes, not alcohol.  They will start at Furin's Bakery, then walk to Georgetown Cupcake, walk to Baked and Wired, ride mass transit to Red Velvet, then walk to Hello Cupcake.  Every event has a time meetup at each place and a plan to get the cupcakes, eat, and move on to the next.  The event lasts from 1-5 on a Saturday afternoon.

These are advertised on twtvite.com and meetup.com  Just an interesting promotional idea that some restaurantors may consider using to help promote thier business.  Do you have other businesses around you with a similar product?  Why not try to promote your business activities through these resources.
