Kettleman City is basically gas stations plus restaurants stop along I-5. It's about 50 miles from Bakersfield, Fresno, and Paso Robles. From an agriculture or possibly oil production perspective, it's significant. But for a specialty need like a Supercharger and on a holiday weekend ... yeah, no.
A coworker went from South San Francisco to the LA area for Thanksgiving. It should have been a 6-7 hour trip, but took about 12 hours.
