Sandwiches, Southern and South of the Border

This trip, Guy Fieri's diving into sandwiches, Southern eats and south-of-the-border specialties. In Spokane, Wash., a lights-out food truck smokin' up real-deal barbecue. In Ashland, Ore., a Mexican joint putting a tasty twist on tamales and crushin' their carnitas torta. And in Bozeman, Mont., a fried chicken haven serving up the bomb bird on the bone and in the bun.
