Two collections that might not be appropriate for living room exhibition: guns and dead animals. Thus, the need for the hunting lodge man cave. You don't necessarily have to be a woodsman to pull off the hunting theme, but it definitely makes things more legit (and increases the cool factor) if you actually killed those deer yourself. You can create your hunting lodge in the form of a high-end log cabin, with a roaring fireplace, bearskin rugs and lots of top-shelf whiskey, or you can go lowbrow with lots of camouflage and cheap beer in the mini-fridge.
Must-have: Did we mention the dead animals?
