My folks and brother and sister still live there. I visit regularly enough. Nothing fundamental has changed. Olatha is still whitebread. N KC still rolls up the sidewalks at 7pm. Johnson county is still a massive cookie cutter burb. KCK is still whitetrash and black ghetto.
About the only thing I noted was they built a new Plaza further out. So the Johnson county people don't have to see a black person.
