Joe D.as you mentioned.
I have stuff in my safe deposit box -
but there are two issues to mention:
... the items in your safe deposit box are not insured - so if you go there one day, and your box is empty (not likely I know), you are out of luck. You can insure the items in your safe deposit box, but at that point why not keep them home?
... you don't get to play with your cards as often 
I have been giving serious consideration to some sort of humongously heavy safe that is bolted to the floor. Not exactly sure the best place in my house / best one to buy / so for now - i stick with the safe deposit box.
edit to say: I also suggest getting a PO BOX. The fewer people who know your address - the better. Very inexpensive. Well worth it for security and convenience.
