Data is from the PennDOT 2012 Unpaved Roads layer. It's embedded it the Mapbox Outdoors theme.
I bought this domain while sitting at a NE PA Trails Symposium in Carbondale, PA. Russ, from the YouTube Channel Path Less Pedaled, was the keynote speaker.
I was inspired to ride on gravel roads while riding my neighbor's Jari. Fuji USA is based in Philadelphia.
