With Bill Gates always hanging around, it's no wonder Seattle ranked No. 3 on Movoto's list of nerdiest cities. Where else will you find a female Hellboy (Hellgirl?) hanging out with a bunch of Stormtroopers. This unlikely grouping came together at the Emerald City Comic Con in 2012. Seattle is also home to the Science Fiction Museum and Hall of Fame. Nerd-tastic!
