Agreed with above. I have never even attempted to crotch the jb3, there is no need. More often then not I won't have a jacket or pockets big enough to put it in, so I walk in with it in my hands. No questions have ever been asked. I've actaully been to a few shows that I saw others doing the same, with the JB3. Takes the paranoia factor right out of the equation. I've been to small clubs, big rooms, and arenas and have never been asked to take it back.
