I was in Pittsburgh yesterday, and 99% of the people I saw had Steeler's garb on, and most yards/cars were decorated. That's a town that just goes crazy with their support, it was fun to experience.
Seahawks!!!!!
Being a former Browns fan - I could never respect myself if I rooted for the Steelers. Plus, I live in the NW and it's all the football we've got!
Rooting for my numbers on the Superbowl Board I am on. Otherwise, don't care. I would put money on the Steelers though.....if I was a gambling person of course.
