I am pretty sure you cannot hunt waterfowl from a raised platform, except over water like a blind on 4x4's in a pond or swamp. I know its illegal here in Maryland and heard it was in others. I do not know if this is state for Federal law.
"If you can't have fun doing it, it ain't worth doing." my motto
There is nothing better than hunting with friends and then crackin' a couple of cold ones afterwards.
