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 could be wrong, but they likely asked because vinyl/PVC is generally toxic to the environment so it was probably a means of asking whether your neighbor replaced the foliage in their yard with a fixture that poisons the ground. I wouldn’t be surprised if the strips in the chain link were vinyl, as that’s a pretty common outdoor filler material.
I think you guys are looking to deeply and it was just a joke about the burnt hedge being replaced with a flammable fence (vinyl).
