I have seen the sites right on the Kern, and have wandered up the "back" way, but that was in November 2 years ago and the road into Sequoia was already closed.
I have every intention of going back, but I kind of figured summer would be pure hell up there for crowds.
At the time I was not set for long periods of
boondocking, but could do so easily now. I'll have to stick that area on my "fall" list. It's only about 3 hours from me.
