Make sure however you build it that it can be secured tightly!! Nothing like a good solid locking doors ect. Might not be as important for a bow only owner but if you do own guns security from children and theives is always the way to go. Heck you probably have a stack of bows worth more than my guns anyway!
Not even my wife can get into my gun room. Just no need and she doesn't care. Nothing like Man Town!!
