THE US POSTAL SERVICE.... HEADQUARTERS.... PARKING LOT
Want to see boatloads of modern day luxury automobiles including full bed F-350's, loaded, with extended crew cabs.. all shiny and glittering... then merely visit the parking lot of the USPS headquarters on L'Enfant Plaza. They arrive at 9:30am daily and then depart at 4pm. Watch closely for all those new and shiny top end Cadillacs... owned by the 'managers'.
