Navy Football (with kids)

We succumbed and took the kids to a football game. I was nervous about the use of the canon for noise during the match (when Navy scored, when Navy kicked off etc), and also the length of the game.
It was a clear, sunny, increasingly hot and sweaty day. aided by hot dogs and cups of ice, we got to the third quarter, but then had to go, as the kids were sick of trying to see where the ball was, or make sense of the game. And the key to explaining the canon? It was a noise making canon...silly us. the issue today was the possibility of bullets/shrapnel, not the noise.
I didn't find I got to enjoy the game as much as last time, partly because of the sun, heat, and lack of sunglasses (yes, we put on sunscreen, but forgot to take the bottle for reapplication...) and also because in addition to my questions about the game, I was fielding all the other questions, so it was difficult to keep track of play.
The other thing was, the noise was inescapable. There was no silence. It felt like a continuous stream of (loud) music or advertisements was coming out. It all just was a little too loud and thumping. Might have been where our seats were? The game is televised, so watching the game live, there are all these random stops where the players are literally standing around, while we wait for the TV man to signal the start. Just seems a bit crazy really. So the game doesn't flow much anyway.
