Thanks for the info everyone

YOU are tireless 'Bug' ! Wish I had something to contribute to augment your efforts, other than congratulations on a job WELL DONE !

BUT, unlike the PAID shills that snap, bite and howl with nothing but negatives, your work has it's reward in all the people you keep alerted to the ONGOING PROBLEM. Thankfully, I built my shelter in the early 1980s and have a filtration system that will take out everything, including nerve gas. I worked with the engineer who designed it, and also wrote the Civil Defense Manual for the USA, Walton W. McCarthy .... Builder of underground fiberglass shelters.
