I was planning on taping it to my nuts or something in that area. If I saw any dogs near the security I would just go to the bathroom and eat what I have. How far away can dogs smell? If I do have it on me, which I probably will, I will make sure of the no metal thing. I don't really look like a pothead or anything, so I am not suspicious looking. I was planning on wearing like a collared shirt so that I will look nice and not look suspicious.
