I'm keeping this short, both because I leave soon to go watch the Steelers take on the Miami Dolphins in the Wildcard playoff game today, but also because a good friend of mine wrote an excellent article about this topic.
Steeler Nation: You don't know how good you have it.
Check out this article on Steel Curtain Rising, from which the picture above comes. My friend Keith lives in Argentina and is a huge Steelers fan, and has quite a following down there. I couldn't have said it any better than he has.
