Bargain hunters, take note. The annual Historic National Road Yard Sale--824 miles of antique furniture, glassware, knickknacks, and fresh produce--returns from May 30 to June 3, 2007.
Locals set up stalls along the National Road (U.S. 40), which runs through Maryland, West Virginia, Pennsylvania, Ohio, Indiana, and Illinois.
Commissioned by Thomas Jefferson in 1806, the road was the first federally funded interstate highway and made territory west of the Appalachians accessible to settlers and traders. Weather-beaten stone mile markers can still be spotted in some sections of the route.
While a speedier parallel highway, Interstate 70, was built in the 1960s, it can't compete with the National Road's scenery and the small-town vibe. You can find suggested itineraries and places to stay through the website BnBFinder.com.
