there are two approches to this that i think could work.
1. (this is not a joke this could work) get some tighty whites and break open a few joints and put ur weed in a small baggie. put the baggie down ur underwear and since the underwear is tight, it will make it so the weed wont fall out.
2. i have a pair of ipath skateboard shoes and on both of the tongues of the shoe, there is a stash pouch that i think is ment for weed. even if they search ur shoes they probably wouldnt notice the pouch.
besides, i went to ozzfest with a bunch of friends and one kid had a half of a g in his pocket he didnt know about and when he got searched, they found it, threw it away and let us in.
