DragonCon is a huge many-medias convention held every summer in Atlanta. How big is it? They have something like thirty-seven (!) tracks of programming, they take over FOUR huge downtown hotels, and they have their own parade on Saturday through downtown. And a MAJOR part of this convention is cosplay. Well, my friend (who I've never actually met, talked to, or otherwise communicated with, but I suspect we'd get along just fine if we ever actually do meet) Jen, who runs a number of blogs (notably Cake Wrecks) always goes, and always takes lots of pictures, and always highlights the best on her Epbot blog. This year, part four of this year's best cosplay features two sets of Oz costumes. And these are not the type you normally see at the various Oz conventions I've been too. So go take a look!
