Good advice. I was traveling with a group in Europe some years back. One of the teenagers bought a sword in Spain. On the EuroStar when we were about to leave Paris, he decides to unwrap it and "play" with it (or whatever goes through such minds). The French gendarmes evacuated the train and held him in custody while the rest of us reboarded the train and left. Eventually, the sword was rewrapped and stored under lock and key so that he could leave France.
There’s no substitute for good old common sense.Seems to be in short supply with a lot of people.
