You'd think with as much time as we spend reading and watching spy tales, there'd be more places like this. The International Spy Museum offers the largest collection of international espionage artifacts ever placed on public display, letting you explore the craft, history, and current role of spy activity. Located just blocks from the Smithsonian museums on the National Mall, it features interactive experiences, as well as artifacts like a Minox camera, a shoe with a heel transmitter, a flashlight gun, and a concealment ring. Oh, and don't forget to hit the gift shop, which goes beyond the traditional trinkets to offer up some spy gadgets of its own.
