US FOSSY 2023 in July 13-16th 2023 — Portland, OR [on-site, no online conference]

Is there a new concern around another wave of COVID in the Portland area or from travelers? I haven’t seen a masks required event like this since last year. Not knocking it, just surprising to me from what I’ve seen in the last few months with the CDC removing masking requirements from their guidelines and even hospitals dropping the requirement.
