Used to go to A-Kon in Dallas, TX every year.
Don't care for them too much anymore. I want doujinshi, cons don't satisfy this. Also find it very hard to find anyone else interested in any of the same stuff, Everyone seems to just be interested in funimation stuff. Vendor area was OK, but I could have bought cheaper, even limited editions of galge for less through deputy service. I don't know, after so much internet a con feels like a trip back to pre-2005. A pilgrimage to comiket/akiba must be made someday.
