I've been one of the biggest supporters of playing the games this season, and I believe my group had renewed our season tickets in the early days of this thing not knowing how long it might last.
That said, I don't think that 30K fans in attendance is a good idea. Like others have said, 30K people in a close quarters and yelling loud - spreading the maximum amount of breath particles seems like a recipe for disaster. It's one thing if a few dozen people get it from this, that's probably an acceptable risk. It's another if hundreds or thousands get it.
I'll be interested in the measures they put in place. Much as I'd love to tailgate, I hope they don't allow tailgating. It just seems impossible to do any of this in a safe way if most of the fans are intoxicated. Keep the lots closed until maybe 90 minutes before kickoff. We're still 4 months out from the first game, so I guess we just hope the level of cases continues to drop and there are so few by September that this doesn't matter. If not, I think a lot of us are going to have a tough decision to make.
