I'd like to second that the Sentry stuff is useful ONLY for paper, not photo negatives, computer media of any kind - basically anything that can't handle 300 degrees for two hours. Also, if they fall over (a common thing in a fire) they can loose their effectiveness as a fire-resistant container. That's why I want an outdoor, off-premise container, and with all due respect to Chris K, I don't trust banks and safety deposit boxes.
