Columbus is closest, but you'd still have to fly, and because it's a 7:30 p.m. game you wouldn't be back in Boston until the next day. It could be done in a 24 hour period, but it wouldn't be fun.
Interstate 70 runs through Kansas City and Columbus, ending in Baltimore, where I am. I just meant it would be great if they came here (which won't happen) -- we've got a nice big stadium, but nobody for them to play.
