I'd definitely go to one. I love to watch anime, and have a deep appreciation for the art form and the media, but I'm not like a die-hard fan.. Kinda hard to describe. I have a huge collection of Anime, but I'm not like into posters, figurines, or anything like that. I do have some Manga though so..
I've been into anime since I was a young kid.. Toonami and shows like Gundam Wing, DBZ, Yu Yu Hakusho, Cowboy Bebop, Read or Die, etc.. I never really looked back after being introduced. My taste has grown wildly since then, and as bad as it is to say.. or good.. I'm so glad that when I met my fiance, when she first started mentioning some of her favorite animated movies, Princess Mononoke came up.. I knew she was one of the good ones.. lol.
We have been planning to go to the Comic Con out of Louisville they have each year, but missed it this year. I may have to check on some actual Anime Cons that are happening local.. Hell, I'd even dress up for the occasion.. You know it'd be a blast.. Like an awesome halloween party anytime of year, with great media, cool people, parties.. I think I'm getting just a little too inspired.
