if memory serves right, a combination of rubber lined tin/metal provides a shield during an emp. the government issues rubber encased laptops for that reason. so what about the possibility of somehow rubberizing the inside of a garage/basement/cabin/ect. that would protect cars/electronics.

as stated above, not the most likely event, but one i would like to be prepared for nonetheless.
we usually have all 3 of our freezers full of food. currently we have about 350lbs of meat, vacuum sealed and frozen. no power? 2 50gal barrels of salt. or the option of making an external refridgerator. dig a hole, about 4-5 feet down, set a wood box/ice chest filled with salt and meat, cover. better than nothing, and it will keep for a while.
fishing is a fantastic survival tool...as long as they are biting, lol. we have a few fish traps, as well as a casting net. i also know how to fish by jugline, trotline and limbline. a 30lb catfish can provide good protein and around here, fishing is good using the above methods. have a place to fish, thats at least semi-secluded, set them and check them.
we reload our own ammo. also, i have a rifle and pistol that both shoot 9mm and 2 that shoot .45. my dad has 2 that are .357. we have around 1000rds of ammo for each, not to mention 300-500 rds of 30.06, 30.30, 223. also, a gross amount of shotgun shells. we hunt/shoot alot....and my dad doesnt trust the government.
also, while hunting may grow harder, trapping is a good tool, depending on your location. but no matter where you live, you can catch coyotes, dogs, cats, raccoons, possums, squirrels, ect. not an appetizing thought, but when survival is at stake, little can go to waste. my dad trapped growing up in washington, so he is showing me how to do it. he has a trap set up on the side of his house, and he lives in the center of town, and usually catches a few animals a week.
here in OK, there is an abundance of squirrels and rabbits. not alot of meat, but every bit will count.
farming: planting crops and having a garden is great, but knowing what to plant, what is easiest to grow in your area, what grows best during different times of year, things like that will count for alot. while we live in a semi-rural area, i went ahead and bought 12 chickens that i keep in a coop in the backyard. they are easy to move, provide eggs, and in a pinch, can be cooked themselves, lol. they are pretty cheap to feed and maintain as well.
heat during winter is provided by a woodburning stove. its currently in the garage, we are trying to figure out a way to mount it in the dining room, and build an insulated box around it with ducting going to different rooms in the cabin. (640 acres of family land in se ok). no way too keep cool during the summer except shade and swimming, lol.
my dad is also looking into a possibility of a wind generator...like a windmill. wind is in abundance here, and it would be a permanant source of energy. also looking into solar energy panels.
and while all of that is great, its dependant on staying in one place for an extended period of time, which may not be possible.
again, knowledge will be your biggest survival tool, along with the will to keep going.
edit: keep in mind little things like hygene. soap, you need to be clean. no shower? simple as a bleach botle or bucket hung from a branch or other high point, holes in the bottom and some duct tape. instant shower. boil water for hot shower. you can make your own soap as well.
toothpaste/dental hygene. tubes of toothpaste are small, cheap and can last a long time. you can also get the supplies to make your own. i have enough to make 2lbs, which is alot.
most important and not really thought of....CONDOMS, LOL!!!! sex is a good mood booster, way to keep warm, and just plain fun. but nobody wants to bring a baby into a post apocolypse world.
