Our secret, there is no better way to break up the human outline then varying the clothes you wear. I wear one type of camo jacket with a different type of pants. My grandfater and dad wear Carhart overalls and a different jacket, most of the time black or another dark color. They say camo is too expensive. We fill our tags every year and are almost never busted by following this rule (and watching the wind). Any other secrets out there?
