Where we are, it just doesn't matter. The total population in the state of Kansas is just over 2 million and 1/2 of them are in the Kansas City area. The wind always blows and you can drive on 2 lane hiways for miles without seeing another vehicle.I know some folks do this sort of thing. I am sorry for it.
Cattle feed lots make more pollution (methane and Co2) than people do here. Worse smells too. lol
This time of year, farmers and ranchers burn off their fields, the smoke is so dense it blots out the sun.
