Knowing how to dress for the weather is essential to persistance as mentioned above.
You're desire to stay in the stand/blind/trail will diminish as the level of physical discomfort increases.
Dressing to fight the cold, or to stay cool, is just as intregal to a successful hunt as the right camo pattern, accurate rifle, and doe in heat urine, if not more so.
Also, I feel a minimum of wilderness survival skills should be mandated in state hunter safety coures, something akin to the Boy Scout first class rank.
