Thanks for that!
I put it into my Magellan!
Seriously, though...is the drive to Barstow reasonably easy for you? Taking I-40 is a great way to avoid LA.
As for 93 - it’s a lot of 2-lane winding mountainous road and has several deadly curves. Obey the speed limits. But the scenery is wonderful and the distance is a lot shorter than going through Flagstaff.
