So keep your money where you can get it but thieves can't!
There are some bullet proof ways to hide things outside your home on your property so that your money is hidden safely from others. One method is called “cache tubes” (pronounced “cash-ay”). Using cache tubes involves getting some 6″ to 8″ PVC drain tubing several feet long, with two threaded end caps. Your stash can be placed in several plastic baggies, and then the end caps can be epoxied in place, or sealed with extreme pressure wheel bearing grease, both of which are also available at your local hardware store. Use a common pot hole digger to create a good hole to bury the tube. If you are burying money, make sure it is wrapped in layers of zip lock bags and throw in a silica pack from the inside of vitamin or supplement containers to avoid mildew or similar smells.
Another way might be to hide things in hollowed out legs of patio furniture, or metal garden furniture legs, or even the hollow legs of a child’s swingset, or fence post. Again, put your valuables in several layers of plastic baggies.
The kitchen has some of the most accessible, natural hiding spots. Take for instance a large flour bin; your goods could be hidden in baggies and buried deep within. Or take an old packaging from frozen food and place your goods in there, and then re-glue the box. Hide that deep in the bottom of your chest freezer.
If you have those sectional plastic shelves, you are in luck, as they have hollow parts as well which are perfect for hiding small items.
If you have some ducts, you could put things in them that are not sensitive to temperatures. Use a string tied to your valuables so that you can retrieve them.
Another trick is to hide the goods in a dummy VHS tape and labeled “Aunt Jean’s Wedding” or something to that effect.
