Oh I've tried. She had no problem going to SU games with me, but refuses to go to the U of Alaska D3 games. I got her into a pick em league this year, that helped a little for NFL.
Her best friend is a "Die hard 9ers fan" (Thats in quotes because the girl knows absolutly nothing about football, and just yells alot). That helped alot. I'm trying to get her friend into College hoops, which hopefully will get my wife involved.
I dated a girl who went to Brockport for a while.. She wanted me to watch one tree hill. I told her the only way I would watch it, is if she learned the starting line up for the Giants, both sides of the ball. She made flash cards. She knew names, numbers, where they went to college, and any important info on that player.. It was amazing.
