Camo is way overratted. Our Fathers and Grandfathers did not use it, and did rather well. They knew the basics, that is often ignored by todays hunters. Sit in the shadows, Sit where your outline is broken up, limit movement, and know which way the wind is blowing.
Sometimes I wear Camo, sometimes I don't. Does not seem to make any differance, except when out in the snow. When moving out in the snow above tree line, you have to be white or you stand out for miles.
