Buddy Valastro and his family's vacation continues as they arrive in Huntsville, Ala., where they train like astronauts at the U.S. Space and Rocket Center. But that's not their only mission here -- they're also discovering local Alabama foods, like Big Bob Gibson's award-winning white barbecue sauce and Bigfoot's Little Donuts' warm mini-donuts with juicy fruit toppings. Then, on their final stop at Dallas Mill Deli, they indulge in a sweet and savory strawberry pretzel salad.
