The speeded up sections are a thrilling ride, where I would be crawling along at a few miles per hour.
Any 2 wheel drive should be able to navigate these roads until they become snow and ice.
The drone shots are the bomb, and in a good way. Thanks for sharing the beautiful landscape and the support crew you had along the way. Trying these paths alone might be worth rethinking. Some of those tight corners demand folding in the rear view mirrors to hug the cliff as close as possible.
Some mountain roads in Baja going up to 7500 year old cave paintings were just as tight. My passengers looked out at thousand foot drop offs out of the side windows with no safety railings. I was crawling along at 3 or 4 mph on some of those corners and did fold in my rear view mirrors for the extra few inches to be gained. Thanks to all here.
