Also known as the National Road, Route 40 has fascinating connections to historic figures, where inns once welcomed west-bound settlers passing through Western Pennsylvania. Farmington, one of the towns along the route, still welcomes visitors, with attractions ranging from The Christian Clay Winery, Laurel Caverns, the historic Stone House, to the vistas of the Summit Inn and the legendary white buffalo at Nemacolin Woodlands Resort. Reporter Dave Crawley follows 40 to Farmington in this historic travelogue.
