I don't think a civilian business would move into Grand Forks AFB if it closed, at least not anytime soon. The communities that survive base closures the best are bigger cities that have grown right up to or around the base. For example, Luke AFB, AZ, if that base closed, which it probably wouldn't, developers would make a mint because Pheonix is growing and land is valuable. Without the Grand Forks AFB, all you have is a barren, windblown, aklai field. Just my opinion.
