There are about 4 million miles of public roads in the United States. 120 of those public roads are considered National Scenic Byways. And 31 of those byways are considered All-American Roads because they have features not seen elsewhere in the U.S. With 20 million annual visitors, the most popular All-American Road is the 469-mile Blue Ridge Parkway through Virginia and North Carolina.
It has no stop signs or traffic signals, no interchange ramps, no commercial vehicles. With no straight section–well, anywhere–and two lanes the entire length, the speed limit is 45mph. But no one is in a hurry. Around every corner is a turnout with panoramic vistas galore. Elevation is as low as 650 feet MSL and goes up to 6000 feet MSL. The roller coaster of a ride probably averages about 2000 feet MSL. The Touareg definitely got a workout pulling the Airstream all week.
