Then I remembered the neighbor with the woodstove. A cheap Yankee, he learned he could save money on trash collection by burning his rubbish in it. PVC bottles made clouds of yellowish grey heavier than air smoke that contained phosgene.
He stopped doing it, before I could leave him some Special Firewood. :-)
So, like everything else, it depends. If someone is burning CCA treated lumber, etc., they need to be stopped immediately.
I did have friends, however, who had a wood-fired baseboard furnace. They saved a lot of money, and no neighbors minded the rustic smell at all. There was one funny thing however regarding low stack temperatures...I was there once, and there were funny snowflake-like things that were falling in the yard, and a roaring sound. I ran outdoors to see a blue flame coming from the chimney that looked a lot like an upside-down Shuttle Launch. Creosote chimney fire.
I'm always offering my buddy my large stack of railroad ties to burn in his wood stove, but he never comes over to get them. I don't know why.
