The City Museum in St. Louis collects a lot of cool and wacky stuff and crams it all into a 600,000 square foot funhouse. A browse around the building and you'll very likely see a couple cranes, old bridges, a human-sized hamster wheel, 5- and 10-story slides, a room of preserved insects, a school bus and Ferris wheel on the roof, and at least one alien dressed like Elvis in a coffin. So it's no surprise they have a room with enormous double vault doors and salvaged safety deposit boxes adorning the walls. Don't lock yourself in.
