I was fortunate to be at the game yesterday. We have had season tickets in our family since the 60s. Let me tell you about the experience...
First off when you arrive in your designated lot there is a police van with tall poles and cameras on top, security driving around in golf carts making sure you have your mask up. I had mask down having a drink by the car, they didn't say anything to me but seen them saying stuff to others that had there mask down outside by their car in a parking lot.
Secondly, entering game was fine. However, when inside during the game was told by the usher to pull my mask up multiple times when having a drink of beer or eating. They charge 15 bucks for a beer and allow you basically to have one sip or bite of food at a time. At least that how it was in my section, maybe we just got a usher on a power kick. I had my mask up all the time, but you obviously can't eat or drink with a mask on. I think at least in my section they went way overboard.
Nevertheless, if we can get tickets to the AFC Championship (if the Chiefs lose and we win to have it at home) I don't know. It might be better to watch at home. It will probably be a better experience. I will be going to the Super Bowl in Florida if we make it though. ..........Go Bills!
