My situation though is entirely different from many of my friends and the ones below, who don't have most of their kids. Given the state is refusing to fund virtual at full capacity now (only 50% per day virtual, and you have to make up the time), I would expect more districts to push resuming.
It's unfortunate that things aren't being pushed back a little longer here though. I have a feeling the upward swing of positivity, cases, and hospitalizations is going to continue to climb until about the 15th from Christmas and New Years. My hope is that after that we're past the worst of it.
For those of you dreading going back for the first time with your groups - procedures, procedures, procedures. We've had cases in our band, but as far as I know we haven't spread it within our band. Basketball seems to be our biggest achilles heel to me. Make sure the kids use slitted masks, bell covers, and distance as much as you can. (Front to back matters more with kids) Follow the guidance from the UC, CSU, and other studies and I think you can make it safer. The biggest thing is wear masks! If you have to get in close contact with kids (ie beginners) N95 masks are a safe bet. We've kept gloves handy and used them with instruments and students.
That's not to say those procedures are full-proof. Medical professionals have been catching COVID too, but at least if you end up back and push the rules forward it will help. We've been fortunate to have kids be really great about their masks over the last months. I think that's part of how we haven't had a major outbreak so far in our school. Part of it is probably blind luck too, and that luck could change on us...
