West Virginia
Unlike most of the people who've previously walked through the gates of the West Virginia Penitentiary in Moundsville, you can be fairly certain you'll be walking out again a few hours later. The imposing Gothic structure was first opened in 1876, but closed in 1995. It's seen riots, fires and the execution of nearly 100 prisoners through either hanging or electrocution. These days, the only things it sees are much better behaved visitors. You can take a tour of the grounds and see the rows of cramped 5 ft.-by-7 ft. cells during the day; for braver souls, the penitentiary also offers midnight tours, followed by the chance to kick around inside the prison on your own until 6 a.m. Overnight visitors are allowed to bring their own food, so there's no need to trade your boyfriend for a Snickers bar.
Admission: $10
