Get a small, fast, motorsailer. Learn to sail. Scout out loacations now between Humboldt Bay California and Coos Bay Oregon. Rig and equip the motorsailer for bugging out of the Marina del Ray area. Once just out of sight of the coast of California, head north. Stop at whichever of the spots you have pre-determined will give you the best chance of making it.
Getting out of LA, and to any place that will support you, is going to be very, very difficult. There will be millions doing the same thing, with many heading east. And those that are east of LA are not going to want Californians encroaching on their very scarce supplies.
Those going north or south will find much the same thing, only heading into other southern California cities that will be hard pressed to take care of their own.
Either Mexico, whose Federales will most likely just shoot you, or northern California and further north, I think, will give you the best chance to actually have a safe place to stage things so you can then go wherever you plan to relocate to permanently. Because the locals probably will not want you where you wind up right after leaving California.
But if you have what you need, and make it clear that you will be moving through, without using any local resources to speak of, they you have a very good chance to get somewhere that you can again take a breather, and make you final plans, just in case they have to change from your original ones.
I would plan on at least three months of consumables, with very good gear suitable for any climate, including extremely cold ones, extremely wet ones, extremely hot ones, extremely dry ones, extremely windy ones, and extremely stagnate ones, and any and all combinations of such.
Be prepared to use fuel to get away from LA, and leave plenty for high speed runs on the trip if needed, and plenty more for maneuvering once you have reached a place you can land. And remember that you might have to check out several, even having checked them out before hand.
Once away from LA and headed north, plan on doing as much by sail as possible to conserve that fuel. If you do have to make a run for it at sea, be sure to have something capable of long range stand off fire to keep pirates or anyone else far enough away that they cannot lay fire onto your craft.
Just my opinion.
