I see your point but I also think it is a pretty big step to vandalize a car in a public parking lot, both inside and out, just because it has a rivals sticker on it.
Seems more deep rooted than that. Also, my feeling is that the rivalry has simmered significantly.
I could see religious affiliation, particularly Mormon in this state with some folks, as a target, much more than hatred of a football program.
Just my thought.
Again, I am sorry it happened and if it was a Utah fan, it was one who showed no class at all.
Both of our fan bases have those who are embarassments. They are likely the vocal minority. I choose to believe it was something other than football.
Seems if it was football, that they would want you to know that you got jobbed by Utah. Yet, not credit given.
