Welcome from a member from Bethany Beach area. I've been riding bikes in this area since the late '70's. The massive development and traffic increase has really affected road riding in this area in a terribly detrimental way. On the good side, there are now numerous parks and wildlife/Eco-centers that have well groomed paths, mostly cinder, and/or short areas of gravel. They range from only less than a mile, and up to 6 miles. A lot of scenic water views.
