My buddy got busted not once, but twice doing the 5 knuckle shuffle. One time on the Notty when fishing was slow. He went back in the woods, took the chest waders down to the ankles and began to do some white water wristing. He did not hear a couple of fishermen approaching. He did however hear tehm ask how th fishing was. Caught in the act, he just said with a smile "pretty slow".
Second episode was in a boat up north. Slow aft fishing so he lay flat in the bottom of his tinner and began some hand to gland combat. A couple of canoers thought the boat was abandonned and rowed up to find my buddy in full swing yet again. OOps.
The best part is that this guy creeps this forum so I will probably hear from him soon. lol
