sat in the middle of a bunch of Utes at the Vegas Bowl and at no point there or while walking into/from the stadium did anyone say anything to me.
My only time at RES was as a USU student going to the USU-UU game and besides some general smack talk no one said anything to me there, either.
Going to Boise St or USU game as a BYU fan, however, was a very different experience. Very different.
