Packer fan here. My wife was born in Illinois and comes from a family of Bear fans... but I married her anyway [Boom! Tzing! I'm here all week, ladies and gentlemen! Don't forget to tip your waitstaff!].
Luckily, almost all of them are sane and we're able to talk football in a reasonable, thought provoking manner. It probably doesn't hurt that I'd actually like to see a Bears resurgence. Don't get me wrong, I want the Pack to win the division every year but I'd like it to be bare-knuckle brawl from beginning to end.
