A good way to see the troop is during one of its mounted parades through Philadelphia, which take place at least three times a year: on the troop’s anniversary, in November; to commemorate Washington’s death, in December; and to mark his birthday, in February. A feature of Philadelphia’s social calendar is the troop’s Border Plate equestrian event, in May, which was inspired by its lively 1916 Mexican campaign against Pancho Villa.
