I asked Mapquest for directions from my home to Poe Paddy State Park, near State College Pa. The route provided sent me over a mountain on a rock strewn trail, not a road, with my RV in tow. It took me three hours to cover ten miles of trail. I could not turn around with the RV in tow and damaged parts of the RV undercarriage. Mapquest is a very dangerous piece of software.
