start penalizing the team 5 yards every time they ring those clangers, and it'll make them nice and quiet.
but one thing i really don't understand is how the rule says that no noisemakers are allowed inside the stadium...yet they still bring them in. i say do a good search and if they're found on someone, DO NOT let them in the gate. tell them they can go back and leave the bell in their vehicle, or they can leave it at the gate. but if they leave it at the gate they will not get it back. of course they'd tell the staff, "you can't do that!" and our staff would counter with, "our stadium...our rules."
then, after we have a nice collection of those idiotic things....we can send them to that cow college down the road.
