Good points... I will definitely continue to hone my mind... It's interesting that you mention that because it made me realize that's something I currently do when I'm out in the field. Looking at tinder sources, natural shelters, etc. when I'm out hunting, hiking, or whatever. I've also thought that there are a couple of things that can be worked on around home, figure 4 deadfalls, practicing and learning different types of knots, maybe even build a solar still in the back yard ( I'm sure my wife would love that! ).
