In America, you either go to a safe school, or a drug sniffing school.

I would NOT suggest hiding it in a locker... Nor even buying in school. That's asking for trouble, because many things can go wrong. Highschoolers, for the most part, are all about ratting you out, no matter how good of a buddy you are.

I forget who posted it, but the post about weed being taped to your shirt in college... SO true. I love college.

And as for the shoe idea, they actually sell shoes with zip up pockets on the sides- Kangaroos, I've always carried my weed in those little zipper pockets, they're comfortable as hell, and they come in all kinds of funky ass colors.
