DaishoCon
I think you should check the daishocon website. It is clearly an existant Anime Convention in Wisconsin that so far surpassed the Numbers that NoBrand Con, the con that its basically a spawn of, in its first year and is going to be around for a while. it had great attendance, it was a well run convention, doesnt have any cons in its time period like the spring summer and even early fall have, and there's really nothing thats gonna stop this con from running.
