The nerd Mecca is almost upon us. Downtown Atlanta will soon be flooded with ghouls, ghosts, zombies, vampires, witches and the most fearsome of all fabled creatures—Trekkies. No, it’s not Halloween. It’s Dragon Con, the annual sci-fi/fantasy convention that happens every Labor Day weekend. The convention will host more than 400 actors, artists, authors and creators who will participate in panels and meet fans, as well as thousands of hours of other programming. Even if you’re not a nerd, there’s something for everyone at Dragon Con. It's $150 for a four-day pass, and individual day passes are available on-site. The parade on Saturday at 10 a.m. is free and worth a day trip to Atlanta alone. For more info, visit dragoncon.org.
