Ski Free yeti!
It's not a proper convention unless the crew from Beat Down Boogie is there to capture all the action. I didn't even know Anime Weekend Atlanta was a thing until this, but I'm glad I do now as there was some pretty awesome cosplay outfits shown off.
All the staples are here. Zelda, Street Fighter, Mass Effect, Alice, Borderlands 2 -- guys someone cosplayed as the freaking Ski Free yeti. How cool is that? Part 1 above, part 2 below, plus a ton of photos over on their Facebook page.
