Never had a problem with someone using a burn barrel, although I never really understood it. Then at our previous house, once moved in we were delighted to learn that the next door neighbor and the one two doors down used them to burn ALL of their garbage, which is illegal. Ironically, the stuff that you are allowed to burn they put in their compost piles.
It was just lovely working or puttering around the property with the smell of burning plastic, paper and whatever else wafting on the breeze. And they had something burning or smoldering ALL THE TIME. If the weather was nice you couldn't even have the windows open. Put up with that crap for about six months and called the county Dept. of Environmental Health on 'em. So, yeah, I'm the diq.
