Even just coming down from New Brunswick to Maine when I was a teenager was extremely surreal. Flags everywhere. Also those metal stars people put on their houses. What's with those?
Oh, I was curious about those too recently since I was house hunting! Apparently they're called barn stars and have roots in Pennsylvania Dutch hex signs - painted adornments that eventually became metal adornments for people who could make them until eventually they just became a standard decoration over time. https://en.wikipedia.org/wiki/Barnstar
