Did you try asking your neighbors?
Well, the ones I talk to, and the ones in my immediate area aren’t the ones doing it; I live in a housing complex surrounded by a trailer park. The ones doing it are never around when they do it. One place that has a burn every couple of weeks is a used-car dealership with an acre of brush behind him. I’ve never seen a soul there, but there’s four or five cars that are replaced every few weeks.
But after people here say it’s trash, I’m sure they’re right. I don’t even want to know what a used auto dealer is burning. There’s some new condos being built that had a burn each of the last three days. I’m not thinking I want to go to a work crew doing something patently illegal (and it is illegal to burn construction debris) and tell them I disapprove.
