Heard a physician liken the efficacy of face masks for blocking the virus spore to putting up a chain link fence to block out mosquitoes. Useless.
Sad.I live 1 mile from the local grocery store. On drive home just now I counted 6 of those light blue disposable masks on the side of the road (and that was just on the right side of the road). Could have been more, but that's the number I spotted. Also have seen two tossed masks out on the trails (BLM land) near our home.
