I disagree with the ''get higher in the tree'' responses. Next time your in the woods look up 15 feet in a tree and then look up 30 feet in that same tree. Most of the time you will have more background at 15 feet. The higher you get the more likely it becomes that the skyis your background. I used to hunt at 25-30 feet and get picked off alot. This year I've stayed around 15 feet and have had only one deer check me out and even it eventually kept going and offered a shot. The only advantage I see to hunting high in a tree is keeping your scent above the deer, but if you play the wind correctly this is not a factor. When you stay a little lower in the tree you have more background and a better shot angle. I used ASAT camo for the first time this year and I think it helps too. Just my $.02.
