Located along New Jersey's affluent Interstate 287 corridor that encompasses the historically well-off corners of Morris and Somerset counties, the village of New Vernon is the most lavish mailing address in all of surrounding Harding Township. Geraldine R. Dodge called it home, the Rockefellers that gave Geraldine her R. lived here from time to time and players and coaches from the area's pro teams tend to settle here before being traded or fired. It's an area that's had its money for a long time and makes no bones about displaying it around Morristown or in Far Hills when "The Hunt" steeplechase races and opulently catered tailgate "picnics" come around in the fall. New money keeps the town's median age at 35 and its streets filled with BMW 328s (No. 2, $35,795) and 535s (No. 5, $53,395) and Lexus RX SUVs, but the old guard still maintains order by piling its prized Austrailian Sheep Dogs into the occasional Jeep Grand Cherokee.
