Trekkies, steampunks, zombies, filkers, furries, goths, Klingons, Sleestaks, Predators, Aliens, and more descend on Downtown for the Southeast’s largest sci-fi con. Come dressed as your favorite character from any number of sci-fi, horror, fantasy films, comics, video games, etc. When it comes to Dragon Con, the wilder the better. The one Dragon Con must-see is the annual parade along Peachtree Street (Sat., Aug. 31, 10 a.m.). Huge crowds 10-people deep line up super early to watch the Stormtroopers, Slave Leia's, Dark Knight-era Jokers and more strut up Atlanta’s main thoroughfare. CL tip: You can't just walk into the convention without buying a ticket anymore. Security now stakes out every entrance, and they’re like the Gestapo.
