The best method for improving crowd noise at Lambeau, honestly? It's keeping the oldest season ticket holders at home.
Before you start flaming, understand that my parents were season ticket holders. It didn't matter how many times I explained the concept of the 12th to them, they simply didn't get it. They were right there with their cronies yelling "Down in front!"
That problem has gotten a lot better with a new generation of season ticket holders, but the new generation presents an even worse problem: selling season tickets online for profit. Unfortunately for us, Lambeau is a bucket list destination for fans of other teams, and that's where untold numbers of tickets end up.
I'm not sure what the solution for that could be. Unfortunately for us also, Packer fans are nice people, with their priorities in order. Everyone wants to come to Green Bay. That's not something you can say about any of our division rivals, for example, or places like Oakland or Pittsburgh or Philadelphia.
