I agree with most of the comments so far. If you have the time, and the longer distance is of no concern, then 395 is a much nicer drive.
I second the suggestions for Alabama hills. You can find boondocking sites there as well, if you are willing.
Another climb, other than out of Bishop, is out of Lee Vining. Not a big deal, but long steady climb.
