Vermont, as an example, referred to as the Cheese Trail
Overview:
" This roughly 280-mile (450-kilometer) loop of the Cheese Trail begins in Plymouth Notch, accessible from I-89 via Route 4 and Route 100A, then follows Route 100 north to Lincoln Gap Road, which descends to Route 7 in the Champlain Valley. Route 7 links several cheesemakers and other attractions along with Burlington, Vermont's biggest city, and connects near the Canadian border with I-89. Vermont's varied terrain of steep wooded hills, broad dairylands, and meandering river valleys unfolds throughout the drive, which skeins together attractions as varied as the childhood home of a president, a superb museum of Americana, and one of the world's largest granite quarries.
