Sarge - My guess is your decoy was made for the shelf, but lots of wires add weight, therefore a thick bottom board helps alot. Currituck. Pamlilco and Abermarle, are not bad if your careful, and have a good guide, or local friend that is Very experienced. Core Sound, in a box blind is where I thought we would DIE (hey we are duck hunters). It Blew A Gale, the Decoys sank on their short lines, and water and waves came in the blind. Redheads and Pintails flew by so close, you could almost touch them... We never fired a shot, and when the guide came to carry us back, he bitched us out for Not Shooting! I said "how would we retrieve the birds?" He very calmly said "Oh I woulda found em". I will never forget the boat ride out and back, ass bustin' and head bangin'. We ate good that night, drank more than enough, and slept very well. Prior to that hunt we spent three days gunnin' Lake Matamuskeet.
Ya, I like NC Waterfowling alot, and highly recommend it to all who love our wonderful (but sometimes Insane) lifestyle.
