I am well aware of the limits of gas masks, and how bad they are. You can do things in them, we even had mopp 4 driving training.
I am concerned because I am 30 miles down wind of Dow Michigan Operations.
The half hour it will take me to load the jeep, and the half hour to drive southwest, mean I and my wife would be breathing some chemicals. Our cats would breath everything, masks may keep some things out of our lungs.
