I have and inside person...so when things are going to start happening, I will get a heads up to get moving.
Pass it along to us to, eh?
Remote is good, as is limited access route. Be sure to check the map for those nuke plants though. That WILL happen if the power goes out for good (regardless of scenario), so you don't want to get the fallout from it.
The circles represent the 50 mile radius, the plumes are based on wind direction of a particular date (and will likely be different, so assume that plume around the whole circle).
Radiation is really the most dangerous right after the event. The risk goes down exponentially even in a short, short time.
Whatever your location, also remember your budget. The farther out you are, the more it may cost to have some things done. A well for instance, is pretty much a necessity, and could cost thousands.
Sounds like this place would be more of a retreat, so if you won't be there most of the time, be sure any preps are well secured, and/or hidden.
Me, I think of preps in categories. Then, within the categories, figure out what you need, and how you will solve the challenge.
WATER - Most important
FOOD - Second most important. Seeds are also good to have. Since you won't be growing anything until you have to use this location. There are lots of foods that can keep for YEARS.
SHELTER - kind of a given in this case, but you have to decide on getting an existing structure or building one.
WEAPONS - Need to protect yourself
POWER - Whether wood, generators, solar, etc., you'll need SOME kind of power source to cook, heat, etc.
LIGHT - Candles, oil lamps, electric lights, etc.
MEDICINE - Stock all you can, but look for herbal alternatives that could be grown too. (more seeds to have). Includes stocking first aid items.
SANITARY - Toilet paper, cleaners, etc.
ENTERTAINMENT - Games, etc. something to make up for no TV or Internet
COMMUNICATIONS - A way to communicate with your family members now that cell phones are no longer an option (two-ray radios, for example)
Everything else is pretty much icing on the cake. YOU will know what your family needs, but we'll certainly be glad to help point you in the right direction or at least a direction.
