I head down from Napa to spend a fun afternoon flying from Oakland to Salinas to Livermore and back to Oakland. For the pilot, this is a flight he needs to make periodically to maintain currency. For me, it's pure pleasure!
We take off out of Oakland and fly down the middle of the San Francisco Bay to Palo Alto, where we turn inland and cross the hills toward the Pacific, flying by Apple's donut-shaped campus.
The clouds thicken inland, then dissipate as we cross the coast over the bay, a truly pretty sight as we fly above them, getting brief glimpses of the ground.
