Ok guys, most of these plans, except those classified as shelter in place lack a key element. Versatility. What do you do when you reach your destination and find squatters already entrenched?
Personally I have a trusted friend in the country with a nice fortified spread, but long distance travel may mot be an option. As a result my plan includes a short range base of operations to prepare. I needed a target that was plentiful, stocked, an relatively fortified, but one that could be breached initially if needed to gain entry. I settled on a home improvement super center. Glass doors can be entered, even if locked, then fortified with the bountiful supplies and equipment inside. Once in you have mid range stores in the form of sports drinks, jerky, and power bars as well as snacks for the kiddies.
Once battlements are improvised, begin prepping weapons, armor, and armored personnel transport from rental trucks. Take time as allowed or needed for prep. Vehicle can be converted to run off of wood gas supplied by ample lumber. Once prepared raid nearby walmart or sams for long range supplies. If capable escape to greener pastures.
If escape is not possible, the garden center supplies seeds and growing supplies in a convenient protected area that should hold you over once short term supplies dwindle. If the situation becomes permanent sprinkler tanks can be converted to gravity fed rain water collectors. Filtration supplies are on hand. Furniture, grills, plentiful propane, and heavy equipment are on hand to provide ease and comfort. There is also the items needed to barter should the need arise.
Ultimately an exodus will have to occur, and you'll have plenty of medical supplies and essentials to get you by including basic meds. Armor up and travel in style. Guns will have to be brought or acquired, but that doesn't seem to be an issue with many here.
The best part is it is an unlikely target for unfriendlies, and the hordes will over look it entirely. Even zombies know home depot is a ghost town as far as employees go. Have you ever tried to find help in the plumbing section on a Tuesday afternoon?
So there you go. A versatile short, mid, or long term facility easily protected and readily available. If the first one is occupied there is always another a block away. The possibilities are endless for the mad scientist and MacGuyver types around here.
My .02 on the matter!
