Camping can be rough in the summer if you aren't completely prepared. Throw in some bitter cold, and the experience can be miserable or even life threatening.
Spending the night outdoors in the dead of winter is not for most people. It takes careful preparation, but can be enjoyable if it is done right. It takes you back to more wild times where people were in a struggle for life on a daily basis. Everything was out to get them, including the weather.
It makes you appreciate the simple life we have. You constantly hear people talking about how hard their life is. I promise, that tune can change pretty easily. One uncomfortable night in the winter woods can give someone a whole new perspective on life. You learn that the word life doesn't have anything to do with your housing situation, religious beliefs, job status or car you drive. The word life represents your survival and nothing more out there. What you had previously called life was nothing more than lifestyle.
I do believe if you go out unprepared, that religion will play some role in most people. You will be praying to whatever god you believe in, that the sun will just rise, and you can warm up. Here are measures you can take that can prevent you from having to pray, unless that's just your thing.
