Michael: (voice-over) It's always a challenge hiding something sensitive that you might need quickly. Any hiding place involves a trade-off between security and access. Hiding something in the sewer main under your floor and it's secure but good luck getting to it. Hide something in your sock drawer and it's easy to get to but hardly secure. The best hiding places are easy to get to, but tough to find. The do-it-yourself version are known in the spy trade as slicks, easy to slip something in, easy to slide it out.
