2.
A borough near Darby, Pennsylvania. Many blacks and white trash live there. Also many self-righteous soccer moms live there and they don't know how to discipline their kids.

A current state of "white flight" is going on as the neighborhood becomes "darker."
"Eew look at that overweight soccer mom with a mullet! Why is she yelling at the coach? Can't she just accept that her kid is playing in a game and fair is fair?" asked Juliette.

"I woouldn't expect too much--she's from Colywn," said Pete.
