Arizona too has listed golf courses as essential businesses, along with barbershops, hair salons, and nail salons. Those last 3 are beyond foolhardy, which means there's lots of blowback on anything being open, including golf. As mentioned above, every countermeasure is being taken at my club, but when I was last there the social distancing was abysmal.
Then yesterday news came that a resident in the community has tested positive for C-19, which means the virus is "inside the gates." Sadly, I am now staying away from the course until May 1st. Too much risk, and I am not willing to take it given my own auto-immune risk factors.
Stay inside. Stay safe.
