Hi, Don, welcome to Martial Talk.
I'm in touch with a few people who run dojos. Everyone's been impacted in different ways. I fear a lot of places won't survive the pandemic.
A friend of mine has been running a dojo and fitness club on the east Coast for forty years. He didn't shutdown at all, just implemented safer procedures for training. He said, "I'm in the health business, we are an essential business." He used to be a commissioner for the state he's in and knows the ins and outs of the political machine. The training has changed, of course, everyone is spaced apart - fortunately he has a huge place. There's no partnering up for drills, no sparring, and hand sanitizers all over the place.
Another guy closed his dojo temporarily for a couple months. First time in twenty something years. Open now, but in smaller groups and more classes. He's been in the Arts forever and was close to passing on his dojo to some of the Black Belts, but has that on hold now, trying to get through to the end of the pandemic and making it easier for them to take over later.
Several other guys I know who had small clubs had to close down permanently. I don't know if they'll ever teach again. Saddens me, good people, good Martial Artists.
