So, yeah, there is a lot of sports-based rivalry and animosity. But there is also a lot of rust belt solidarity, and Cleveland would be the first city to go on the warpath if anyone tried to take the Steelers out of Pittsburgh.
We fight so much because we're so much alike. I know a lot of folks in Pittsburgh were actually cheering for the Cavs to win.
Oh, and that post-victory "riot" we were supposed to have? Five total arrests in the entire downtown that night -- less than the average.
