So we've established that LA residents don't want to be bothered with traffic when attending an NFL game. What else keeps them away? Long concession lines? Loud noises?
It keeps some away, it obviously doesn't keep them all away.
By the way, the main reason I don't like to go to games is because of the loudness. It's the same reason I don't like concerts, but you just keep on looking down on everyone from your pedestal.
