Re Bus or Train travel: My elderly M-I-L insists that she was treated to a TSA-style pat-down and metal-detector search before boarding a Greyhound Bus at the terminal just South of Downtown Houston. BUT, a knowledgeable Friend, who lives up near Cleveland, TX, tells me that he frequently travels by bus with his concealed handgun and has had zero search or inquiry. Does anyone know the real deal on this? Also, I have been told that CHL carry is forbidden on AmTrack, but that there are no searches or detectors; anyone know about this ?
