Keys

"If you must hide a key, hide many keys with it. Take some old spare keys that don't fit anything (everyone has some of these around the house), and put them all on a key ring with one key you truly intend to hide. If someone actually does find the keys, they won't know which one is important. Or they will go on a wild goose chase trying to fit outdated keys into imaginary locks.In the past, some people attached a misleading key chain to the keys, or made up individual key chains for each key the person hid to throw others off track..."

"Metals can rust. Water levels can rise unexpectedly. Magnetic media such as computer disks and audiocassettes and even video cassettes will melt in hot weather. Your worst enemy may very well be Mother Nature!

For these reasons, you have to choose a storage container wisely. Regular cardboard boxes are bad because they aren't impervious to rain. Milk and juice cartons or jugs are better because they are used to contain liquid.

A plastic bag sealed tight with tape will keep out wetness, but if there was any moisture in the air inside the bag, it could condense in cold weather and you'll end up with a sealed bag of water droplets soaking into your precious cache. Libraries sometimes have this problem with outside book drops. I've seen compact discs that have been deposited into a book drop one night, then retrieved the next morning by library staff. The CDs were soaking wet, literally drenched with water that had condensed overnight on the cold surface of the CD and jewel cases. Once water had accumulated, it would run off, allowing more water to condense on the cold plastic cases. This was not damaging to the CDs themselves, but it did damage to the accompanying CD booklets and other books in the drop."

This is what Dennis said.
