I doubt that many of us are willing, even if we had the $, to devote all that much $ or time to shtf preps, because, basically, we just don't believe it'll happen, or at least, not real soon. For those with some time and desire, but not much money, I suggest a dugout near your town or city's largest water source. As long as it has trees for cover, it will suffice. If your digging, etc, is done at night, without showing a light, it won't matter whose land it is, but in the interest of staying legal, look first for National Park, State Park, City Park, Bureau of Land Management land. Then look for utility-owned land (RR companies, mining, paper, lumber, you know, places where people rarely go. Start with a hole not much bigger than a grave. Sorry, but it's all that's feasible, really. It will take nearly a week of nights to create just that, and discretely dispose of the dirt. Another week of nights will be needed to cache the 55 gal drums of food and gear. This is a lot, but when you figure that it saves the need of an SUV and tons of risk involved in trying to go a long ways after shtf, a bit of work is no big deal. If you do this, you've got a place to go, and you can reach it by bicycle, or maybe even on foot, in one night of travel. If you stay in the dugout, emerging only at night, and only to get water and dispose of wastes, you will be most unlikely to have any confrontations with desperate people. That means that you won't need to spend thousands of $ on guns, ammo, and training with same. Just a $50, used Marlin 22 autorifle and a pocketable 9mm will suffice. If you go 4-6 feet down, the temp in the lower 48 states supposedly stays between 40 and 80 degrees F. That is a big help. A hole that is 3'x3'x9' is all you need. You will have little to do, if shtf, but enlarge the hole, anyway. This big a hole will be a lot of work, and you'll have to shore it up for long term viability. Look into plastic or fiberglass, because wood rots. Treated wood may be good for a decade, if it's not too wet in your area.
