Wanderlust. A pressing desire to know what's beyond the next horizon. A yearning to see something other than one's own backyard.Travel writer and novelist Gail Hulnick has a weakness for the good old-fashioned road trip. Oh, she enjoys 75 mph on the Interstate, but her favorite road is the winding two-lane through the mountains, the seldom-used strip of asphalt that connects the small towns or the old desert highway that gets you there slowly. Rumble Strip USA invites you into the passenger seat for travel stories and photos from sideroad journeys in 25 states including the view from the top of a Vermont mountain, the nostalgia of vintage gas stations and motels along Arizona's Route 66 and the rhythm of a twisting byway through Washington.
