Although the general consensus seems to be that I should get a safe, I don't have much room in the house.

mtwoodson, however, brings up an interesting possibility which is to put a safe in the garage. My garage is attached and gets a little bit of heat in the winter (because some return air ducts run through it) and stays relatively cool during the summer (the outer wall is 1.5ft thick stone). It does get a little moist, however.

Would I run into rust, moisture, hot/cold problems in the garage? Or would a golden rod take care of it? (I seem to recall a post about this way back when, but don't recall the outcome.)

A safe in the garage really would be the ideal solution, but I don't want to take any chances.
