well, are you downwind or upwind?
but it doesn't matter. the problem is people who live in valleys. when high pressure builRAB, the polluted air does not escape due to an inversion layer.
Minnesota doesn't have that problem, there is the jet stream to blow everything away.
i used to live downwind of a spice plant, and early in the morning you could smell it for miles due to inversion layer.
see I don't buy that premise. I think if they wanted to they could increase money for enforcement of air quality monitoring and how much scrubbing they do and I think results would improve.
