Post-action report. I flew the first part high to cross the mountains then drifted down to 3500 across the Imperial Valley (Thermal) to Blythe for a fuel stop. Then I flew Blythe to Deer Valley at 1000 AGL along the I-10 freeway. I have to say I preferred the 1000AGL part and I had a place to auto all the way. 3:45 total and gorgeous weather. Winds aloft to 6000 were light and variable!! Bad luck there.
Thanks again, this was a most excellent discussion. I learned a lot by "listening" to all of you!!!
