We're social animals so it's not surprising that we gather with others who share our interests.  At these decidedly strange, occasionally bizarre, conventions and expos you can share in the fun and come away with a whole new perspective on human behavior. From celebrity impersonators to horror fans to ardent UFO adherents,  you'll meet people you'd never run into at Starbucks.
