I have actually been to a single digit game at Chiefs stadium back in the 70s. The things about such games is where you sit and the wind. That day I sat in the front row of the upper deck — and it was wind in my face.
I can’t remember anything else about the game. There are other cold games I remember, such as the Christmas Day six quarter game. (I lost my voice)
I believe, the Chargers had a "Barefoot Kicker"...
