I started there because that is where the road is closed to motor vehicles. With COVID happening and parking at the top being limited and trails narrow, the road has remained closed all season, which makes it a dream to ride up.
Finally the parking lot at 14,160ft. Not so bad really, a pretty easy grade most of the way and I must be well adjusted to the elevation.
I didn't realize this road is the highest paved road in the US. Since I'd ridden my bike, I was wearing my road shoes which are rubbish to walk in. I decided to bare foot the remaining 105ft to the real summit. It was worth it for the views, the high light of the ride really, I imagine a regular summers day would be crowded.
