The only time my neighbor starts a fire in their back yard is when there is a red flag fire warning. We don’t have many of these warnings per year, like one or two. On these days, they have a fire without fail. Yeah, they’re a libertarian. Loves Rogan and Musk. Fucking dangerous, these people. Adolescent contrarians have more functioning logic.
I’d call the local Fire Marshal.
It is Missouri. Even in a red flag situation, having fires is only discouraged. It would have to represent a visible threat, ie, unattended or spreading beyond the pit.
That may be but the fire Marshall has skin in the game unlike the cops do. They don’t want to see one of their guys die in a structure fire so it behooves them to at least have a chat with this clown.
Plus, getting it on the record that someone called it in might be important later if things spiral badly. Hopefully calling stops this fire, but if not, maybe it stops the next one.
I’d still call and ask if they could knock on his door. Keep “discouraging” him until he gets it.
Have other neighbors also call in and ask for help.
