San Francisco Cart Project

About SFCP, from their website:

The San Francisco Bay Area is home to a wonderfully innovative local street food culture that is growing extremely quickly through its combination of technology and mobile, sustainable, food. The SF Cart Project seeks to complement the research of people interested in starting, or expanding, a street food business of their own by providing a relevant central resource for documents, information and community awareness regarding the often confusing (and occasionally contradictory) process of starting and running a legal mobile food business in the Bay Area.
