I'd be happy to help make this happen in Columbus, Ohio (that's pretty central - either within a day's drive for most or serviced by most major airports). I've got two event spaces in mind for events like these (one that cost would cost about $5K for two days but is bat-shit-insanely cool, and the other that is not but cost only in the hundreds. If everyone is ok with a low-key but still quality event the first year, I'll kick it off. Let me know. Judging from the #'s there's definitely interest.
