Yes, we registered. We got a notice on Friday (or maybe Thursday) that we could show up at Walmart at 12 noon for our vaccination. Evidently they space people out because there was no one else waiting in line.
Although my morning appointment was canceled by the storm, Sally's afternoon appointment wasn't. I took her to her appointment, and asked if there had been any afternoon no-shows. There was one, so they slotted me in to take that spot.
