I live on the Delco/Chester County line in Chester County.
A guy from Poland wouldn’t understand the differentiation.
My work brings me into Wilmington, East DelCo, Philly, Allentown...
So even though my neighborhood is fine, I have to interact with “youths” far more often than I care to.
Haha, I’m envious. I’m on the dividing line between east and west Delco. Chester is a little close for comfort. Thankfully, I live on a high, steep hill that is fairly defensible.
