I doubt most city people/preppers could survive for a long period of time unless they actually have lived in a primitive setting before, especially in Northern climates. Best laid plans or not. I lived in upstate NY for 7 years in a house with just a wood stove and gravity feed water from a well in a house that was built in 1789 and had never had power or any other modern conveniences sense it was built. My first wife and I lived there for 7 years and 4 years after our first was born and we did just fine. Some things were a bit harder and took more time, but over all we really did OK and it really made us closer, it was a happy time. Many times I kinda wish I'd continued to live that way actually, life was truly much simpler back then.
But I was a country boy and was raised up in a very small city, actually still the smallest city in the country. And woodsman-ship was a big part of my upbringing. With a big woods behind the house I learned many lessons in. I grew up in a family that kinda held on to the simpler/old ways of life for many generations being of native decent. My great great Grandma wouldn't even allow my folks to put electricity in her house and still hauled her own water, cut her own wood, hunted,fished, made and drank "Apple Jack"sometimes to excess,so I'd heard, and smoked a pipe into her 100's. She had to go to a nursing home after she fell off the roof @ 104 while trying to fix a leak, but was in perfect health till then. It may have been some Apple jack that caused that now I think about it, never noticed being only 5or so at the time! I'm sure it was all those modern conveniences that lead to her demise.
,,,,Stubborn cuss she was,, She'd hardly ever let ya help with anything. And she was bound and determined to take care of herself. Our family have all been tough old birds and never went to modern to fast and mostly lived a simple life till just before I was born pretty much. I think my Grand Pa was the first in the family to actually have a car,electricity and central heat when he got back after WW1, and is the same house I grew up in.
Hell many places here in Vt didn't even have power and phones till into the mid 40's early 50's in some paces. Actually in the NE Kingdom some places still don't, but mostly by choice now. Maybe that's why most older native Vermonters can fend for themselves pretty well when things get tough,,they always had to.
Damn!!!!! I AM OLD!!! Gezzzzz
Most folks aren't going to be able to just jump into being a "rugged individual" over night without some life experience and background. Best laid plans or not, when there's no modern conveniences and one truly has to live off the land, that's what will really separate the true survivalists from the preppers IMO.
