There are loads of food trucks out there, but I don't think many of them are made of old school buses. The Burger Bus in Santa Barbara, California, is just that: a school bus that sells burgers. In an interview with The Santa Barbara Independent, co-owner Michael Gardner explained that he and his wife Cheryl picked a school bus because other options were too expensive (new trucks), too old (used trucks), or not large enough. Their burgers are made of 100 percent grass-fed, hormone-free beef from Shalhoobs and other locally-sourced products, such as the jalapeño jelly from Mama’s Preserves on their CB&J (cheeseburger and jelly). And for vegetarians, their menu includes falafel.
