I would think that if demand increases with the Canadian border opening to vaccinated US citizens that more locations (Walgreens, CVS, etc) will start offering the testing. There are lots of CVS and Walgreens locations so I’m not concerned about finding a testing location, it just may not end up being the location closest to where we’re staying. I’ll definitely secure an appointment as soon as I can as opposed to hoping for a walk up appointment though. Looks like the CVS I’m looking at is booking a couple of weeks out.
