Ammo cans in the woods
If you are wandering through the woods and come across a metal box painted army green with a handle on top and bright yellow letters stencilled on it with the words "cartridge", "26.5mm", "10 round clips" and so on and maybe even an orange warning sticker with the universal explosive pictogram on it, what would you do?
