1) Asheville to Roanoke (via Blue Ridge Parkway) 2) Spend the day at Roanoke. 3) Roanoke to Charlottesville (via Blue Ridge Parkway) 4) Spend the day at Charlottesville.

Dear Robert, Sunrise is defined as the moment the top of the sun's disc first breaks the plane of the horizon in the morning, and sunset is when the top of the sun's disc sinks below the horizon in the evening.
Because the Sun and Moon appear as circular disks and not as points of light, a definition of rise or set must be very specific because not all of either body is seen to rise or set at once. Sunrise and sunset conventionally refer to the times when the upper edge of the disk of the Sun is on the horizon.
