I have two teams. I lived in Pittsburgh for 25 years, through the Super Bowl years of the 70's, the blight of the 80's, now their resurgence with 6 (count 'em) Super Bowl rings. I still wave a Terrible Towel and have my Stiller banners up. They're hanging in there in 1st place, but not sure how the season will play out.
I've been in Philadelphia since '89 and started rooting for this plucky little team in the 90's that wasn't very good, but had a lot of heart. Kinda like the city. We went with season tickets in the 2000's and haven't looked back. This year is the worst with all the promise and, well, you know what happened.
