I just found this link on Guy Kawasaki's G+ stream.  Everything you need to know about starting and operating a street food business in NYC, and I was thinking there's no end to the stories that can come out of being a street vendor in the City. Meeting hundreds of people every day, some of them regulars. The protag—the owner of the food truck or pushcart--can be a retired private investigator, an alien, a vampire, an impatient classically trained chef with a love for yakitori. Think what you can do with humor, information gathering, a front for crime or the CIA, horror--a street food vendor on Sept. 11.  What if we turn this vampire/undead thing on its head and suddenly every book and magazine publisher is getting dozens of stories centered on the street food business in NYC?  That would be worth writing and submitting a couple stories itself.

Who's with me?
