Tucson - San Diego / Beechcraft Bonanza A36 (N3758W) / VFR

An unusually long flight from Tucson to San Diego, flown mostly on autopilot along V105 and V66. I did stray from the airway over the mountains east of San Diego to follow I-8, which led me through lower terrain and eliminated any need to climb above my constant cruise altitude of 6500. It was dark when I started out, and the sun was up and shining by the time I finished a bit over two hours later.
