My company held an event here and we were fortunate to take a tour of Heinz Field. Not a sports fan, I didn't expect to enjoy the tour but took it anyway since it was free. Boy was I impressed. We were allowed an opportunity to walk down to the field with the tour guide who provided us with wonderful, including what happens with the big Ketchup bottles during the game (alert: do not walk or do a cartwheel on the grass! You will get yelled at). We then toured the underground, including the locker rooms, which I expected to have that smell that took me back to my high school days, but it was surprisingly clean. It was certainly well worthwhile, even for someone not into sports.
