I went to Costco a couple mornings ago and it was't that bad. Most people seemed to leave enough space and they do have the checkouts well done and line spaced out. Of course that was first thing in the morning so I'm sure it is worse as the day goes on.Yes, outdoor work (while still practicing social distancing) is probably a great thing for both body and soul. I went for a 45 minute walk outside yesterday and it felt great!
My better half is returning to work this evening... it'll be interesting to see what the current situation at Costco is. (Probably going to "hoard" some coffee while I'm there, as that will probably be the next thing with empty shelves.....)
