Ozarks, good call on the BPS Air mesh, I have that cap...it is nice and cool and the lightweight polyester dries quickly.
As for good luck charms, I have a 8" spike antler shed in my vest that I found in South Dakota in 2002. I was hunting with my friend Tony Hansen, who is editor of Michigan-Out-Doors magazine. We were standing under a tree discussing strategy on a henned up gobbler that had just flown down when he looked down and spotted a spike shed. After he picked it up I glanced over his shoulder and saw the matching shed laying in the dirt about 20 feet behind him.
Tony killed that bird. We both scored Merriams gobblers on that trip and both of us have carried the spike sheds in our turkey vests ever since.
