I have driven up 138 many times it's not that harda drive. Of course I am a bit demented. I thought nothing of driving my Truck TC and horse trailer up Black road in the Santa Cruz mts. Grade got up to 14% width varied from two narrow lanes to 1,5 lanes on nasty hairpins that required you to hug the outside fog line whether it was on the drivers or passenger side to get the truck and trailer around. Climbs 3000 feet in 5 miles. But you get used to roads like that when you live in the mountains and drive them every day
