It's hard to imagine a more macho-flavored chunk of the Philadelphia area than lower Delaware County. Ride west from the Delaware River refineries to Baltimore Pike's strip malls and you'll pass through a vibrant blue-collar world of bars, parish gyms, street-hockey games, hoagie joints, Eagles flags, Phillies hats, Flyers decals, and rowhouses whose sports-crazed occupants are as rock-hard as the brick facades.
