Wife has concerns (as do I) about that amount of time indoors with poorly circulating air.

In my research, a lot higher risk of transmission indoors after prolonged contact.

They are taking the following steps:
1. Screening everyday (meaning asking are you sick, or been in contact with a sick person, etc)
2. Temperature checks everyday
3. 4 courts will be used, so some separation between kids
4. Coaches in masks
5. Equipment sanitized daily (whatever that means)

We have a family vacation with HCBW's parents (in their 70s) in a few weeks, so, wife is worried about screwing that up.
