Whether or not ducks are killed does not have anything to do with whether it was a successful hunt.
Success is when I didn't do anything to ruin the hunt, like blow on a duck call. Oh, I have them. I have a growing collection that makes me smile.
Success on a hunt is also when waders don’t leak, the gun was not dropped in the water and shells ejected. The ducks and the gunsmith celebrate a jammed gun.
I celebrate the breakfasts and dinners more than the hunt. Duck camp is as much a hit because of fellowship and food as shooting a limit of mallard greenheads.
