If they can put Foxboro Stadium out in the middle of nowhere with one road in and out of town that's not even a highway, then a Batavia location right off the thruway could make sense.
As a Rochester season ticket holder, I am very much in favor of Batavia for my own selfish reasons, but I'm honestly doubtful it happens. However, the more I think about it, the more logical it seems, especially considering the Foxboro model. I'm sure other teams have done it too, thrown their stadiums way out in the middle of nowhere.
One advantage to the location is that it would allow for preserving our tradition of wide-open spaces for tailgating. As others have pointed out, the tailgating scene at more densely-packed urban stadiums is kind of a bummer. I've been to Charlotte and Atlanta in particular. Instead of a big community vibe, it's just small groups scattered around various private lots and parking decks.
