This is my first post here! [:D]
I remember early on in my Turkey Hunting days reading an article about cammo, its use and how its used to break up your outline (the goal of cammo)
Well the article stressed the importance of mix and max patterns. The jest of the article was that the bottoms should match the forest floor and and the top half should resemble the greenery around you. So early on in the season, with little ground cover, your pants would have a more fall looking pattern, while the uppers would contain more green colors since the foilage was starting to fill in.
I mix and match trying to match the surrounding greens, browns, grays, leaves or wateva! Seems to work, but movement is still key too.
