I started hunting ducks right at 50 years ago. It was considered unsportsmanlike to shoot a duck on the water unless you were killing a cripple. Anyone caught shooting a non wounded duck on the water was labeled as a "slob hunter". Back then if you saw another blind working a group of duck, you had better not touch your call unless the duck pealed off and quit working that blind. Back then is was called "blind courtesy" Now a days, I have seen times when the other blind will shoot at duck to flair them just because they are not working their blind and they are like "if I can't have them, then nobody is going to kill them".
Times have changed in the waterfowl world and not for the better either.
Nobody hates a duck hunter , like a duck hunter
Decades of voting for the lesser of two evils has gotten us just that.....
