Wilmington and H'burg doable from NYC. All those youngsters moving up. And Wilmington has the great Claymont Steak Shop a few miles north of downtown.
Sadly, the Brass Rail steak shop, Allentown, has closed. My old boss, Art Lee, took me there every time we drove to Rockville in the late '90s, and it stuck whenever I drove I-78 to DC. Art became a programmer at the GE Erie plant in the late '60s, and had grown up in Allentown, PA.
