Hmmm, thanks for the suggestion, beaglegod. The rubbermaid container I got is one of those "Latchables". So it's got a latch on each side and you have to pull the latches out in order to take the top off and you snap them back closed when you put the top back on. It seemed pretty secure to me. Do you still think I need to take any extra measures? I definitely don't want to take any chances.
