As I walked past UCSF Parnassus (a combo medical school+hospital), there was a big sign out front saying DRILL IN PROGRESS. Behind that sign were some big tents set up in the emergency room parking lot. Those tents could hold, say, a large influx of sick folks hoping to get tested/triaged/etc. I was pretty glad to see UCSF folks getting ready, figuring out processes and such. I was doubly glad they had that DRILL IN PROGRESS sign out front, otherwise I probably would have chickened out on taking the rest of that walk.
