Charged up, yes; but exhausted, very yes!
U.S. 395 heading either direction is a long, dark, mostly straight-for-miles it-all-looks-alike hypnotic road at night, esp. when you're exhausted. Like others above, I don't know how I ever made it to where I was staying (in the Palmdale area) from Lone Pine when driving there the same night as my hike day. I would seriously consider staying in Lone Pine, clean up, sleep, relax, eat, etc. and then head home the following morning refreshed and with the sunlight on the road (395 is a very beautiful drive along the mountains, which beauty is wasted by driving at night when you can't see it).

If future generations are to remember us with gratitude rather than contempt, we must leave them more than the miracle of technology. We must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.
- Lyndon Johnson, on signing the Wilderness Act into law (1964)
