PVC. A shovel and a spruce sappling. A box of WBB a payday will keep the bad guy away. Dig a hole to plant the tree. Dig a narrower hole in the hole. Take a short length of PVC pipe, glue a cap on one end. Place ammo, a firestarter, a glass jar with a few petroleum jelly soaked cotten balls in the tube and glue the cap on. Insert vertically into the hole and plant the tree over it. Someone with a metal detector won't be able to sweep over your stash because of the tree. You can make like Johnny Appleseed and bury these stashes anywhere between your home and your family's emergency meeting spot if you want. The lighter you travel, the faster you travel.
