My 3rd graders has been on the bus and in school since Aug 11. So far so good. 6th grader is in school half the time, e learning other half. 1 positive case reported across the k-8 in that time. A couple dozen cases at the 4,500 student high school, which is a total hybrid model. Pretty tight pods and lunches. My 3rd grader only comes into 'close' contact with 24 other kids. She's also been tested. Negative.
Meanwhile volleyball goes on, I wear mask 100% of time, kids can remove during play, many still wear them. We had kids stay home on precautionary measures, but no big issues.
