Anyone arguing against ever wearing a mask at this point is willfully ignoring the advice of 99% of the medical professionals in the world and choosing the medical advice of Facebook and Youtube. It's really not even up for debate at this point.
That said, I'm vaxxed and will not be masking up outside for a four hour football game. I'll take the calculated risk in an outdoor setting.
I will be putting on my mask when I go into the indoor, crowded, hot, damp, nasty azz bathrooms at the stadium. Just seems like a place a mask might just help a little.
