I should probably add that the "waterproof box" isn't really 100% waterproof -- there are a couple of small holes near the handle that would allow moisture to escape.

But I also like the idea of those silica gel packets. Might have to pick up a couple.

I too thought about putting my trunk kit in a duffel bag, but decided against it for now. The box fits just right in the corner of the trunk and still allows me to carry my work gear. I think a backpack would be even better still -- I may roll up a small one and stash it in the trunk.

Then if it really hit the fan I could walk with my survival goodies.
