These tunnels were always a challenge entering sheer darkness on the Wing until the eyes adjusted then back into blinding daylight
This road should be on everybodys bucket list. I have traveled end to end 6/7 times. My standard route to Carlisle is to pick up the parkway N of Ashville NC and travel to Front Royal Va. Have done that the past 10 years. I allow at least 2 days for that trip, 2/3 days end to end. There are nice camp grounds along the entire route and decent motels off the major cross roads. Be sure your brakes are in order....LOL.
