The town of Floyd, west of the Blue Ridge Parkway, about an hour southwest of Roanoke, has only one stoplight, so it’s easy to find The Floyd Country Store (540/745-4563), which is famous for grilled cheese sandwiches, bowls of chili, and its weekly Jamboree ($5). Every Friday starting at 6:30pm, the display cases are pushed aside for an hour of gospel music, and then the floor is given over to bluegrass music, flat-footing, clogging, two-steps, waltz, square dancing, and shuffling feet.
