Masks are a great option... if we had any! Here in Minnesota, where 3M is headquartered, we can't get them. The feds have basically stolen them for use elsewhere. I might also add that the Mayo Clinic is based in Minnesota and is one of the leading research hospitals working on testing and cures.
The mask shortage has prompted some people to make their own. Some have gotten pretty creative! One lady made one that looked like a huge open mouth with tteeth. Maybe there will be a market for designer face masks if this goes on long enough.
I'm getting ready to do a post about redneck masks. lol. Dang, they should start becoming available since so many companies are making them now to help out, pretty soon we'll be flooded with millions of them for each city.
