This is a place where the border may run right through one's home. Anecdotal but true: in the 1970s a search was done in the house of a businessman there who was suspected of arms deals and money laundering. Both Dutch and Belgian authorities were involved but the house seemed clean. Until an unlicensed handgun was found in the master bedroom which was on the Dutch side of the border. The man then got mad at his wife because the gun had originally been hidden in a drawer in the living room, on the Belgian side where no license was required. Wife: "Yes but that was where the kids might have found it". Married life can be very complicated.
