Scenic 99 miles on blacktop Skyline Drive in Shenandoah National Park, Virginia. You can buy your national park pass ahead of time online recreation.gov. Also obtain free backcountry permit at https://www.recreation.gov/permits/4675336  Backcountry permit is required for overnight staying in the park, it registers your car.  Skyline Drive does not have a wide shoulder. Most cars were courteous slowing down driving around me and I also did not mind running on the grass. Everyone I encountered were very friendly.
