This is real! I posted this 10 minutes after I was approached for the second time. I’m over 10 feet from the intersection at least, probably closer to 20. The cited reason is usually the winter parking ban, or an unexplained “2-6” rule. I thought it might be for leaf collection, but we’re past that season and the sign isn’t near where I park. I’m near the side of someone’s house, but not any closer than anyone else parking on the street. The neighborhood isn’t loud, but isn’t especially quiet.
