In a hunting magazine, I saw a picture of a guy in super expensive "State of the art " camo , with his back to a tree ,blending in perfectly with the tree. I burst out laughing. "Impressive camo " I thought, but what would be even more impressive, would be the intelligence to skip the expensive camo, and sit BEHIND the tree. Then, one can pick one's nose, scratch ones ass, turn the page in a book, or fiddle with the MP3 player, with no chance of being seen by a deer in front of the tree. No camo can blend you in better . The tree makes a great bench rest for your shot, not an option with the tree behind you. The side of your face peeking around it makes a pretty small object for any deer to see. Or, you can make up a small periscope out of ABS plastic fittings ,and put a couple of ears on it, to make it look like a squirrel peeking around the tree. Not much chance of alarming deer that way.
