Doesn't make much sense to me. How would they even retrieve ducks if they did shoot something?
I understand that not everyone can have nice things like boats, and all the gear required, but if shooting from the boat ramp, they must at least have a canoe to retrieve... if so, they should easily be able to paddle down river a bit and away from traffic areas.
However, I've seen stranger things... last year, in my ground blind, there was a guy with his son who decided to hike in a setup 50 yards from me. I shot a mallard and he started to run it down as if it was his... I was a little pissed at first, but when I realized the guy was wading through chest deep water with jeans and a flannel, I thought to myself... "this guy can have the damn thing, I'm the F**k outta here" Couldn't believe a guy went swimming for a duck. Thank God November is here.... time to get our swamps backs. :)
