Have you ever swam at a place that says "Lifeguard not on duty, swim at your own risk"? I think this policy should be how they let people into stadiums. Hopefully by September, the numbers will be so low, that the people arguing for half full stadiums are laughed at and, by then people should understand better how to NOT GET SICK when in crowds.
I don't feel like a senior, but at 63, I get a cheap coffee at Hardees, so there I guess I am. Anyway, I'm fit enough to park downtown Knoxville (because it's free) walk a mile or more to the game, tailgate with my old fraternity buddies, climb to the upper deck - and then the post game tailgate, and the walk back to the car and the drive back home (200 miles each way). Age better not be a filter. And money either.
There isn't a crowd limiting policy they can come up with that won't piss off half the ticket holders. The only fair thing is an empty stadium and if that happens, I am sad that we have become a nation of snowflakes afraid of our shadows. So called experts dictating ridiculous rules.
