I heard our smoke from the Northwest is on it’s way to New York. I blame several factors. One is the lack of logging, which thinned the forest. When I was a kid you would see log trucks on the road all day long. We had two major saw mills in the area. Now there are no mills or logging. Therefore the forest is getting overgrown. The logging companies, back in the day, would replant what they cut, thus creating a new forest for years to come.
Just my theory anyway.
