I worked at Wilmington CC and went to public school, so you know where I belong.
I think New Castle County has the most private schools per population of any county.
“South of the canal” is quite a different world than stuffy New Castle County - a lot more Trump voters. Drove up to SNJ the past few years from the Carolinas via the Chesapeake Bay Bridge. Southern Jersey is generally like south DE - quite rural, many hard working, conservative people. Big money has been buying up the real estate in Delaware coastal towns. Getting to where middle class DE people can barely afford to visit their own beaches, let alone own a modest place.
