Seriously? I'm new here and don't want to piss anyone off.

It's a container that keeps out moisture, and has a fixed amount of space within it. You can store anything you want that will fit in that container. A tow strap for instance, cold weather stuff like gloves or knit hats, food or water bottles, tools or hardware, maps, beer, herb,.....whatever man.

I'm not being a smart ass, Peace brother.
