RE: using a crossbow?
Big Country - Here's an idea ........ pick your weapon. Make it a rifle tag, a muzzleloader tag or a bow tag and you cannot hunt in the others seasons. Do that and you'll really know who loves their equipment and who's doing the 2 season hunter tango.
Will that cure the being unethical part ? Partially, because if you knew you could only hunt with your bow, maybe that'd be more incentive to get good with it (be it compound, crossbow or recurve/longbow.
