When enroute to L.A. Keep an eye on the weather, this time of year the L.A. Basin can close up with costal fog. Whiteman Airport (KWHP) is just North of Burbank, but its a small GA friendly airport with cheaper fuel than Van Nuys or Burbank. If the basin closes in, check out KWJF in Lancaster. Usually a good option if the basin weathers in, and a short hop to the basin when it clears. Avalon can also get weird with fog. I have seen half the runway VFR and the other half IFR. Avalon has a VOR and GPS approach. As mentioned the runway has a hump in the middle that is notorious. Many pilots have locked up the brakes or ran off the runway thinking it was the end. Make a good fly over recon of the runway before you set up your approach. They have a landing fee, I think a fee for additional passengers, and the bus to Avalon is 25 per person, oh and its too far and steep to walk to Avalon. Also while you are down that way check out Chino airport KCNO. Its a great warbird hub, theres the Warbird Museum, and Flo's Airport cafe. Enjoy
