As stated above, you shouldn't have any problem. In the early days of the RENT, the "tennis ball Nazis" (so named for the green color of their windbreakers) would threat patrons with ejection for the following "infringements":
-using a telephoto lens on an SLR camera
-trying to bring in cow bells, air horns, or other noisemakers
-in the early days of cell phones with cameras, refusal to give the Nazis your phone battery before game & picking it up at customer "no service" post game. Imagine how on call medical personnel felt about this decision.
-bringing a hand held tv to the game. We had two 9-10 y.o. kids in our party. They were watching Res Sox-Yankees on the hand held. The Nazis demanded the batteries or be ejected. We gave them the batteries, waited until they walked away, & put the spares back in. The State trooper nearby said that if they came back to call him & asked the kids the score of the game.
Times HAVE changed but the no noisemaker policy is still in effect.
