True, the USBC and BPAA could work harder to lobby state officials to reopen centers. The challenge will be when state officials go back to their respective departments of health for a "medical opinion", who then consult with medical experts, only to be told it is too risky (indoors, close quarters, shared social space, etc.) Just like the restaurant and bar industry has been lobbying for months for businesses to reopen only to be denied time and time again.
When my doctor heard yesterday during my annual visit that I had been bowling, the tone of the visit changed and the doctor was not pleased. I was told it was risky, and that as a result of being at the bowling center just 1 day a week it places me in the "high risk" group for catching Covid-19. I was then given a full explanation of what I am to do when, not if but when, someone on the league I am on comes back positive. It was kind of alarming and almost made me want to stop bowling. I am going to keep bowling, but going to work even harder than I do already to stay safe while I am there.
In any event, I can imagine medical experts would have a similar discussion with state officials who would then deny bowling centers from reopening. So it would be a battle of the USBC and the BPAA against the state health officials. I am not sure there is enough empirical data available for the USBC and BPAA to be able to show the statistics surrounding how much communicable disease is (or isn't) spread in bowling centers. Without scientific data backing them up, it would be a tough sell for them with state officials.
