Basement always
Thieves don't like to go into basements for fear of being cornered by the owner if they catch em down there. Any where in the basement out a site in a locker is good enough for me. I would not hide them in a closet, too obviious. Before the law changed and we didn't have to lock em up by law I did get broke into. It happen 2 weeks after I came back from hunting. I left my rifle on the stairs after coming home for quit a while , lucky for me I hid it before the break in happened under the bed. They never found it, thank god I still have my 250-3000 99EG in excellent condtion. They did tear throught the bedrooms and closets, but they never looked under my bed. They took a lot of electronics and crap, but not my 99, and I still have it today shot 4 running deer with it in 2006 hence the reason for my avitar logo.
