This is an interesting tool:

It accepts an address or zip code, and returns a list of nearby markets and restaurants that carry local food, along with lists of CSAs and farms. (One result for this little town: Chipotle.) For a responsible consumer traveling to an unfamiliar place, this tool could be a great asset. The site can also map a route and show you ethical food options along the way. Very impressive!
