It was an April night and I was about 10. My dad and I had went backpacking on a fishing trip. When we got to the stream it was getting dark My dad set up 4 railroad ties and then put dead grasses up next to them. Pulled a tarp out from them and that was our shelter I got so cold that night that a gallon jug of water we had setting ready for morning had frozen solid. I never got cold. My dad taught me so many outdoor skills. Forever Thankful
