One interesting source of survival information is the homeless. I always pay attention to what they are carrying and over the years have picked up some good ideas. The picture that is shown below is from a homeless camp not to far from where I live. Some of the people have lived there for years. Now the weather here is not bad it only freezes a few times a year, but we do get heavy rain in the winter.
You will notice that this individual has one tent inside another and they are both covered with two tarps. This is probably for two reasons, rain and cold. This is a good example of why you need good gear and lots of backup. Regardless of how fancy your gear is, it will deteriorate with age.
A while back we were camping on the coast and had three tents with us. A cheap one I bought wholesale for $4.50, a Walmart tent and a fancy REI tent that cost $400.00. During the night, it rained hard. One tent leaked, you guessed it, the expensive one. It was new and had a bad seam. This is why you need to be sure and use your equipment and become familiar with it.
And don’t forget lots of redundancy, everything fails in time.
