Winter is always a bit harder on some folks than others, but for us preppers, sometimes it is doubly so because we cannot be outside taking care of property needs, working on projects etc. We can still take this time to prepare and plan. This is the perfect time to do some web surfing and find out what others are doing and see if it fits into your plans or not. One of the projects that I am in the midst of planning for next year is an emergency room. Of course not like that of a hospital, but a small room, probably about 150 or 200 total square feet built somewhere on my property. There are several different ways to do this, but the one that I am thinking of using came from a hotel that I read about that used concrete drainage pipe as separate rooms. They come in 8 foot sections that are 12 feet in diameter. My plan is to use about 3 or 4 joined together in a row buried about 1/4 to 1/2 of the way to ensure stability. They will be able to withstand almost any natural and most man-made disasters, and since I live in a tornado-prone area anyway, it will be a good investment. With their high thermal mass, they will be able to be used to keep cooler and warmer without any use of energy and arranged in a row, even a small fan or heater should be able to influence the temperature to a pretty good degree. As far as security, with only one entrance security needs will be greatly reduced. The cost will not be negligible, but for what you get, it will be money well spent.
