MASKS or NO MASKS? Does anybody have a clue on the effectiveness of masks? CDC has waffled on the issue so many times, and everybody has a different opinion. Is there even a right answer?  Stores have signs about "laws" and "guidelines" but I want to see it in writing. Which law? Whose guidelines? I'm sick of needing a mask to go into a store, and now that my office is about to open, word is that masks will be mandatory. I'm an RSA (registered smart ass), so I'm digging through my Halloween costumes. I have a Scream mask, but that'll suffocate me.  So far I've been using a scarf that somehow always manages to slip down. 😁  Anybody have any suggestions?
