For a period of about two months last summer my church discontinued singing because of the COVID. It really hurt, because my church has an excellent music program and a really magnificent pipe organ. The organist did his best to make up for it, but it wasn't the same. After a while, though, additional research showed that, as long as everyone was still wearing the masks (we were, and are), it wouldn't matter. And so we are signing again. As far as I know, nobody has contracted COVID as a result of our singing in church, and certainly nobody has died from it. I'm reasonably confident that shouting on a ride, while fully masked, would similarly be inconsequential.
