Places NOT to hide things ...
~ In the master bedroom - anywhere in that room. This goes for the bathroom, too.
~ The freezer / refrigerator / pantry. Pretty much forget the kitchen.
~ A safe that can be picked up and carried. As above, the safe has to be #1 - too heavy to move and #2 - bolted to the framing of the house.
~ Under drawers, in books, behind pictures, under the mattress.
~ Items that will probably get stolen all on their own - the TV, the computer, the car that is left in the garage, etc.
~ Anywhere in your home office.
Places to consider:
~ Buried in the yard.
~ Buried in the crawl space under your house.
~ Buried in the loose insulation in the attic.
~ Between the floors of a two-story house. Remove a light fixture. Put the small items in a protective box in the cavity between the floors, replace the light fixture.
~ Among your child's toys. Children's toys rarely get thoroughly searched unless the criminal has lots of time.
