I just came back from Mexico with a little shampoo bottle full of K. (Of course this is only a fictional story for all you pigs out there). I crotched it and kept it on me the whole time. If I were to take a few hits, I would crotch those too. Don't put anything in your luggage because they might go through it. I brought G in a Pepsi bottle on a plane before and drank it on the flight, nobody checked the bottle.
