I practice my prepping skills a lot! I make knives from stones. I make fire from bird nests and shaving wood with the "knives" I make! I can cut grapevines with those knives, to make snares! I can fish with Mesquite tree branches (sharp thorne's) with bait I know how to find! Yes I would have a hard time in a brutally cold environment surviving, but I make sure I know how to do what I can do!!
