look for someone to give them a free ride.
The point I would make to your upper notes is that it's a choice. The individual has to make it. If they choose to come they can't sue unless ND actually did something that was true neglect. Like fired all the janitors and didn't clean anything. Someone that chooses to go into a public place should know there is a probability they will get sick.
This is the same poor stance where guys get a concussion from playing football. You know the risk when you sign up. You choose to sign the contract and play knowing the risk. You can't just sue because something bad happens.
There is no way on earth ND will or should tell people they won't get sick or make any claims that insinuate such. There is no way they could possibly uphold or guarantee a claim like that. That's idiotic for anyone to even expect to receive that type guarantee and they should just stay home. Yes, social distancing is a good thing in situations like this. It can and does work but is not a guarantee. It just lowers the probabilities and people that just to participate even in a social distance setting have to understand the risk involved and they are making the choice, therefore they can't point the finger after because something bad happens.
It's a poor system we've designed. No longer do people have to assess risk. They just do whatever and sue their way out.
