While I don't drive to Palmdale, I do drive to Edwards AFB on another Lockheed project. I've been doing this for 5 years, which is a short time compared to some of the other engineers that live up here

My commute is actually a bit longer in terms of time and mileage to EAFB, but the beginning and end of it (leaving from and going to home) is all about the same. Either SR2 to SH138 to 165th St East, or Big Pines Highway to N4/Largo Vista to SH138.
Another alternative would be to bypass N4/Largo Vista entirely, and keep going down Big Pines Highway to Big Rock Creek, then take a hard right onto Bob's Gap Road, which takes you through another pretty valley, and meets up with SH138 at 165th St East.
Just be ever vigilant of both the roads and the other drivers. SH138 can be dangerous, since it was never designed to take the type and volume of traffic that it now handles. Yeah, it's improving, but it will be a while before it becomes a four-lane divided highway through the desert (if ever).
Also, many of the mountain roads don't have guard rails, and there is a rather long drop to the bottom. Save some vacation days for those snow days when it would be shame to go to work...
With all that being said, welcome home!
