Besides providing tourism info, the visitor center also welcomes bands from across the Americana genre for WDVX's Blue Plate Special, a free concert series at noon Monday to Saturday. Very helpful staff. There's a free downtown walking-tour pamphlet available, too, with detailed information about 70 buildings.
Pick up a two-hour parking pass for its car park while you mill about downtown on weekdays. You can stay all day on Saturday and Sunday.
