This year, the smoke from the California fires was actually much worse in Colorado & Utah than the bay area proper. You can't necessarily escape this by moving.
True, but it's going to be bad some years. This year I expect an outright disaster, considering we've had the driest winter in 150+ years of recorded history. Probably it's going to be unbreathable at certain points.
On rethinking my statement I've realized I should encourage the Californians to stay in California and not spread communism to the rest of the country. So yeah, you can't escape the bad things by moving, stay there.
