This is missing dozens of conventions.

I New England alone you have Another Anime Convention, Pop Cult Anime Convention, Bakuretsucon, Animaine, Anime Boston, Queen City Kamakaze, Portcon, and Connecticon just to name ones I have been to recently.

I get some of them are small, but Connecticon is a four-day convention that sells out like 5 hotels in Hartford, its pretty big, definitely bigger than either of the conventions (and it only indicates one) that take place in Portland Maine.
