I hope they get the record and that it feels as good as they hope it will.
I lived in KC for almost 2 years, back in the late 90's. My wife and I rented a house from a sweet old couple who were absolutely nuts for the Chiefs. They traveled to Wisconsin for the Chiefs' training camp. They wore Chiefs jewelry. They were decades-long season ticket holders.
We haven't thought of them in quite a while, but during this past offseason my wife suddenly realized that we got our Super Bowl victory before they did. That made me a little wistful for our old landlords, who would be in their 80's now. If they get the loudness record, I hope it makes them happy.
