Great idea to target people who go to the Arena for other things -- although the rodeo folks might feel right at home!
Quite a few signs were shown, and the announcers talked about it throughout the game. We were pleased to see that much attention paid to the issue! And the signs looked great, too. I think they showed them more than the terrible towels, even.
Wish I were still a western Pennsylvanian so I could contribute to the cause.
