Speaking about as definitively for Minneapolis fandom as anyone can (i.e. not at all), I'll point out that all Minneapolis needs is about a dozen Worldcon-running-level fans, of which we have approximately me.

The facilities are fairly great (indoor connections to more hotel rooms than anybody else, mostly about 2 blocks away from the Convention Center). It's the people to run it that are lacking.

And if God wanted me to win the lottery, I'd find a ticket.
