If you've got enough fuel, punch your buggy into drive and cruise southeast into St. Mary's City for Charter Days Weekend. Among the highlights: an open house at the 17th-century state capitol, tours of the square rigger Maryland Dove and a jousting tournament (beginning at 1 Saturday). There'll also be lots of traditional music and crafts demonstrations. Hours are 11 to 5 Saturday and Sunday. Free.
