My guess is that they will, the situation is similar to that in the Metrodome. The reason we get to play there is to be a dry run for the Twins, so I guess the stadium will pretty much operate as it normally would.
I'm pumped for this game, it should be the biggest crowd the Gophers have had in a long time. Many will be there only to see Target Field, but some of them might get a taste for Gophers baseball. Plus, it should get some national attention.
