My personal favorite Texas cons are A-Kon and AFest, although I've heard Anime Matsuri is amazing (it's just too far away for me and happens to fall on a major religious holiday =___=)!
I'm looking for any JPop/KPop cosplayers, or cosplayers interested in singing and dancing, in the DFW area! XD My dance group is looking to expand before the summer con season, when we have a bunch of performances lined up! So if anybody is interested/knows anyone who would be, please drop me a line! ^o^
