The old timers (very successful oldtimers) that taught me to hunt used these skills along with their green woolen pants, red and black woolen jackets and their barn boots to stalk and kill game for years before any of the new gadgets were thought of.
Aw now come on Coastie. You know its pretty cool to enter the field all decked out from head to toe in camo. Camo hat, camo balaclava, camo shirt, coat, pants, underwear, socks, boots, bow, sling and gun. Heck, can' t even see yourself on account of so much camo. Someone needs to begin research on how to add camo to our breath.
