Hi John... Been that route many a times, but I'm confused. Edwards Air Force Base is in Mojave / Lancaster not Bakersfield. Anyway... From Bakersfield to Blythe , I would just shoot straight down I5 to San Fernando and catch I210 and follow to I10 around Pomona and go straight to Blythe to Houston on I10. Now from Edwards AFB that's a different story. You can leave Edwards (Mojave) or Bakersfield if you want to go through Mojave on hiway 58 west to Barstow and cut south on I15 to San Bernadino and use I215 to cut over to I10 and your on your way to Blythe and on to Houston. Long Trip, but the southern route is the way to go this time of year. Good Luck and enjoy.
