Hmm, you diverted to Nut Tree because Half Moon Bay was fogged in? The Nut
Tree is 58 nm away and there are literally more than a dozen closer
airports: San Carlos, Palo Alto, San Jose, Reid-Hillview, Oakland, Hayward,
Livermore, Gnoss Field, Petaluma, Sonoma Valley, Sonoma Skypark, Napa, and
Buchanan. Note: I didn't count SFO. Since the chances of all 13 of those
airports being closed at the same time for weather is practically 0%, why
did you choose such a far away airport to "divert"?
