SPretire22, I think we can hope for the expiration of a mask mandate by October 2022. I only say that due to one observation in my hometown last week: I went with husband for his followup with a large orthopedic facility, and was shocked that they have removed their mask requirement. This is a major outpatient facility, and a month ago masks were required. Our church, which has a committee that keeps their ear to the Covid ground, has now made masks voluntary.
Our pizza place still requires customers (and employees) to wear a mask, but not all fast food places are as strict as they were a month ago. Our state's daily numbers (cases, hospitalizations, and deaths) are down to single and double digits from the previous day (vesus in the hundreds and thousands six months ago), though the health department head honchos encourage us to generally not let our guard down.
By next October all ages will have been vaccinated (if they choose). That should help.
Whether any of this will translate to Las Vegas, casinos, flights etc. by then is anyone's guess, but I see the things I mentioned as hopeful signs. Good luck.
