Here's a video taken by a mountain bike rider, riding from Whitney Portal down to Lone Pine.
He even rides past the Whitney Portal Hostel, the Lone Pine Film History Museum, and stops at the Best Western Frontier Motel.
It's fun to watch and remember that road. He clipped out parts, so it doesn't cover the entire distance.
If you go to the video on YouTube, this rider has also posted videos of rides in Bodie / Mono Lake
, and in Death Valley
