I went to USU from Ricks. I was always a BYU fan, even there. Most people were awesome. Even die-hard Aggies. Most harumphed a little when they found out I was a BYU fan, but didn't give me much crap. There is definitely an inferiority complex there. I would still love to have my kids go there.
I loved everything about my USU experience, except the 93 football game. Not only did we get beat, but my dad and young sister (also BYU fans) came to the game, and the atmosphere was very foul and crude towards the Cougars.
