New Yorkers have a reputation for thinking they are "better" to be sure! LOL (But somehow the NY flag and "I Love NY" don't have the same impact as what y'all seem to have up there!)
I know that old family Virginians feel the same way. Course, here we also have folks in the south who fly the Confederate flag, but not the stars and stripes! (Damn Yankees!)
There are a lot of interstate rivalries as well. Ohio tends to make jokes at West Virginia's expense, that sort of thing. I've lived in 4 different states now, and each thinks they are the best! lol
