It’s Geek Pride Week in Atlanta as thousands of fans take over four downtown hotels for Dragon*Con, an annual celebration of science fiction, fantasy, comics and gaming. Where else — OK, other than San Francisco or New Orleans — are city streets shut down for a ragtag parade of zombies, superheroes, robots, Klingons and Middle Earth dwellers Where else can comic book collectors rub shoulders with movie stars, vampires, alternate-history speculators and Harry Potter look-alikes, all while taking part in a lively game of Godzilla Bingo The whole thing is a bit of a shock to college football fans in town for the season-opening game between Alabama and Virginia Tech, one of whom called it a “freak show.” But those aliens grow on you after a while.
