I keep some important papers, passports and such in a firebox in the safe. Sort of belt and suspenders, I guess.
What a couple of guys have said about a determined thief breaking into what we call a safe is certainly true, but that's not why I have a safe...er, residential security container. My aim is to protect against some tweaker who's looking for stuff to steal to make his next meth buy or to safeguard the stuff inside in case there's a fire or flood. It's sort of like locking up my car at night - if somebody really, really wants it, a locked door isn't going to stop them.
Besides, there's plenty of other stuff not in the safe that's awfully inviting to a thief.
Well we don't rent pigs and I figure it's better to say it right out front because a man that does like to rent pigs is... he's hard to stop - Gus McCrae
