Correction from the HH6, on the coffee. We bought "Franklin's Finest" freeze dried coffee for instant coffee (720 servings for $77....for the 2 of us, at one cup a day/morning, that's nearly a year's worth), we have 2 or 3 or those. GROUND coffee CAN go rancid, so the thing we packaged in Mylar bags was coffee BEANS. Coffee beans can't go rancid, as the "oils" aren't released until ground. We packaged up several pounds of the beans, with a manual grinder and coffee percolator to use when needed/required.
We're up about 600ft above the valley floor (safe from anything but BIBLICAL floods). We live at the end of a cul-de-sac. We have an attached garage for the cars, and a detached garage, for storage as well as my drums. We see deer at least once a day, have a good location for a garden if needed, and have 6 medical professionals that live around us. Basically, we've made the decision to stay put, we're not bugging out. Neither one of us in GREAT shape and I'm not sure that we could really go any place that would be better than what we have now. The ONLY thing I truly fear up here is fire, and I put a metal roof on the house because of it. Not only do I have about 6 cords of split Oak currently, but have a whole forest around me to cut down more if needed. Unfortunately, that means I have a LOT of fuel (including pine) around the house for a wild fire to feed on and NO local fire mitigation to stop it.
Everything I talk about/recommend is based on the above. We're staying put and acting accordingly. Our 2+ years of food stores, the ammo, the firearms; ALL of it is to help us stay in place and survive. Take ANYTHING I say with that in mind. When my wife was traveling 50 miles each way, up to Mechanicsburg to work at Naval Support Activity Mech, every day? We had a possible "Get Home" plan in place for her, with her getting on the Appalachian Trail and heading South, and me getting on it and heading North to meet up with her and bring her home. Now that she Teleworks (Medical telework agreement) every day? That's not even an issue (we have a 2013 Dodge Ram Big Horn with less than 20,000 miles on it, to give you an idea of how much we "travel").
If you live in the middle of Los Angeles, most of what I've said has NO bearing on you. There's NO way I would try to "bug in" after an 8+ earthquake, waiting for everyone around me to run out of everything and bein looting everything around them. If this is YOUR situation? I feel for you. I have NO good advice of what you should do, well except get out NOW while it would be easy to do. "Come OUT of her, my people" fits in here somewhere.
