well i tried a spot this morn that i know is good when its foggy and only took 3/4 box of shells, well 1 hour later and 6 ducks later i am out of shells. I pack up and head down the trail and lowand behold there is 2 shells layin on the trail, so i dropped my gear grapped the shells and stood there and not a minute later here comes one flyin over and i dump it. Thanks 2 someone who dropped 2 shells i got a limit of mallards (kinda cool.)
