On the ground — what to expect
The leg clocks 55 road miles via US-101 → CA-37 → CA-29. Typical drive-time clusters between 75 and 100 minutes. Wine country classic. SFO Marin bridge to Vallejo then CA-29 north through Napa town. Fri 3-7pm adds 20-30 min. Flight tracking fires on wheels-down, so the sedan is already queued at San Francisco International's pre-arranged ground-transport kerb when the first checked bag drops onto the carousel. Common drop-points inside Napa Valley: Yountville, Oakville, Rutherford, St Helena, Calistoga.
