RE: Taxidermy question(s)....
I guess I would say yes, because if my sole purpose was to get meat. I could shoot any deer that walks by my stand, but I have been holding out for a mature deer. I of course am in it for the meat too, it's just that I get plenty of it during gun season so I can afford to hold out on a big buck. Plus, who doesnt like the look of a nice mount hanging on their wall? I plan to have my downstairs full when I am an old man and have my own house.
As far as duck hunting goes, I would shoot a Wood Duck strictly for the mount that it would make, I could shoot mallards if I was going for meat quantity.
