Some of the places I’ve lived have had stark cultural differences from one county to the next. You can cross an invisible line and suddenly everything is different, from the people to the liquor laws.
Maryland is like that - the sales laws vary per county. Not a lot and there is mostly commonality, but enough to notice.
Then DC and Virginia is different too, so it feels even weirder. There is enough cross state line traffic that people forget they are different states.
I believe it.
