Pick the biggest tree possible and do not be outlined against the sky. No matter the camo, when you are "skylined" the chances are much higher of being seen by deer. Being parallel with trails is also paramount. This time of year especially andfacing the deer trails, well we stick out like a fungus on the side of a tree. I also start hunting on the ground more often using brush, fallen down trees and stumps in the background and foreground. You might be amazed at how many deer will look into the trees as they slowly make their way along trails toward feeding areas after encountering hunters all season.
