We did a Zoom show over the weekend. Fortunately, we have a full band here at the house—me on guitar, my daughter on bass, my son on drums and my wife on piano. We also had another family come and set up on our patio, and i ran cables out there to add them into the mix—and thus were added cello, keys, BGs and another guitar. It was great, and felt pretty safe...
...and then my wife went out with a bottle of wine—maskless—and talked with them for a couple hours. A couple people in the other family were maskless at that point, too, though we were well spaced out. Probably safe enough, as this family has been conscientious, but possibly not. That's the line we all walk these days—a line that's invisible, and apparently up for debate. Is it worth it to hug a friend while wearing a mask? With depression as a secondary epidemic, maybe so.
It's all risk/reward. I've done so many things over the last 6 months—took an amp in for repair, bought strings, ran into Rite-Aid for chocolate—that I did as safely as possible, taking all precautions, and STILL I lay in bed a couple nights later, kicking myself, thinking "Was that really necessary? Is M&M's the hill I've decided to die on?"
Back to the topic at hand...I could see plexiglass being another useful layer if, say, someone watching the band sneezes through a 1-ply mask. Also a useful layer if any maskholes storm in and start shouting about their rights. Every little bit helps.
