We're going to SEKI in mid June and I've got a question about what needs to go in the bear box. I know that all food and scented items need to go in the box, but we've got a 5 gallon water jug that is round and blue. It's obviously not a food cooler, but would a bear think so and therefore should it go in the box? What about those 2 1/2 gallon clear water containers? Can you leave those out?
