I continue to check my little dashboard of #SanFrancisco COVID numbers each morning to decide whether to go inside a hardware store to shop for a replacement emergency flashlight, if say, a power outage reveals that my old one apparently stopped working some time back. I track three numbers; lately all of those numbers have been rather low, below my "pretty-safe" line. Thus will I shop inside with carefree abandon (albeit wearing a cloth mask because that's pretty easy).

graph charting three numbers over the last couple of months. two of the numbers have been consistently low+safe for the past couple of months: % positive of PCR tests and number of positive PCR tests. The green line was above the 'pretty-safe' level for a few weeks, but has dipped much lower over the last couple of weeks

Someone looking at the data for the past couple of weeks might gripe: Why didn't Larry blog about this dip sooner? It looks like that green line went low a couple of weeks ago. Alas, not all the data was in; up until a week ago, the numbers up on the California Department of Health site looked like they were hovering a little above the "pretty-safe" line. Someone might also gripe: Wow, there's a couple of steep drops in that green line in the last couple of weeks. Larry should smooth that data out over several days. That is the smoothed data, though. COVID-in-wastewater data is super-spiky.
