Our neighborhood in PA was like that! I would sit on the porch because the front door never closed. I joke that it was like a movie set with parents and kids everywhere, criss crossing the street - some made bon fires in their driveways. It was so cool!
In our neighborhood, they had parents from five houses all sitting together on their cul-de-sac around a little fire pit with orange lights and all kinds of decorations and they called it Halloween Island. The kids just walked around the circle of parents and didn’t have to go to the doors.
