Yeah personally, Ohio would be best imho
For a few reasons, Its more central to the people who already plan on going, more central then Manchester, NH because at least that way, it would cut most travel times in half, maybe even more. I know it would cut Zkat's travel time down by 95%
You would get to visit Columbus, Ohio Home of the bucks
THe convention center I posted is rather large, Lots of food courts, three or more floors of open space ^_^ lots of room to roam around and whatnot.
Look into it
Plus, I betcha we could all just stay in the convention center over night, I know thats what we did at Marcon 40, Just slept in the rooms
