How rude can you all be. These girls work hard to get to this point. There are two groups that go. Pop Warner and AYC. My daughter cheers for AYC and they are all warned that if they do not behave the will be sent home. It has happened, parents had to come get them. I have seen many ill behaved children at disney parks and they are not all associated with group sports. Lets all strop blameing the cheerleaders.
Since kids generally feel the "power" to be obnoxious in numbers and POFQ was used as overflow, I wouldn't worry too much about noise in overflow. 'Course, I've been wrong B4. The excuse that kids will be kids never washes with me as a parent. I'm pretty sure people are talking about well beyond normal child/adolescent idiocy.
