Yea you can find furries there, I found a guy dressed in a giant orange cat suit (kinda scared me but meh) But here are a few near me check them out. Also know of one? Post it's web site here ^-^
Another Anime Con - Manchester, New Hampshire -
http://anotheranimecon.com/Port Con Maine - South Portland, Maine -
http://portconmaine.com/ (WOOOO Like 20min or so from my house)
Anime Boston - Boston, Massachusetts -
http://www.animeboston.com/MTAC - Nashville, Tennessee -
http://www.mtac.net/Mind you I will be attending all of these conventions, yes dressed in my wonderful particals. Each con is 3 days long starting on a Friday and ending Sunday. Most (least the ones I've been to) gone on 24 hours the whole 3 days. Also helpful tip for thoes who've never gone to a con and are planning on going to one. Reguarless if you have someone to go with or like me end up going by yourself, you WILL have a grand time. And guess what if you stand next to someone long enough either they will run away screaming from you, OR HEY LOOK YOU MADE A NEW FRIEND! Muahahaha.
Saddest thing is I know nothing of half the anime's out there, but hey I still have a great time.
