^I don't believe that's the case. If I'm not mistaken, I thought Cedar Fair was just totally prepared work with the state into guidelines. But as far as I know, there's nothing official from the State. It's just the parks trying to lean on the state a bit.
Which I'm all for... I said from the very beginning, Orange Tier should be fine. Yellow Tier, the current standard for park opening, may not happen for years, if ever (even with vaccines, since they'll be a non-trivial population who won't get them---likely the same people who don't wear masks in the first place, so I suspect Covid will exist in some form for a long, long time).
