Well, this is if you travel. Usually when I go on my trips I carry a Violin caufin with me. The coufins really don't cost much, I think I picked some crappy one up in a flee market for like 10 bucks or something. I don't own or pay a violin by the way. But in airports they won't pick you out to be sniffed by a dog. A friend of mine who is a musicianist gave the idea and it seemingly works. But not in all countries I heard, most western countries it'll work. I have no idea how to pack you shit without REALLY getting caught by a dog. But apperance is the first step. But the peanut butter idea, does it really work?
