I work the Central Mohave Desert from Palmdale to Victorville and all of the area north from Boron to east of Barstow to Hector and north all the way up the 15 past Baker close to the CA/NV line. It takes me a month to cover the area so I miss a lot, but I’m always at least passing through the area along the 395 almost daily to get to the other places. I’m mostly on dirt roads except when I need to make some time to the farthest places and then I’m on the I58, I395, I15 and the I40.
Everyone thinks I’m a little weird because my favorite area is out around Newberry Springs along the I40 and I would move there in a heartbeat except that my wife would probably leave me.
All of my favs in this gorgeous desert....Newberry Springs is good (not as nice as closer to the Preserve or the area around marker 7 through 19 off of Ft Irwin Road--right around where that Bison lives, have you seen him?)....All perfect...I actually can not think of any parts you mention that are not beautiful in each of their own merits....
