I used to belive that the term inlaws ment relatives who lived in provinces that had seatbelt laws. Back before 1988 or 89 Alberta had no seatbelt law. When we went to Saskatchewan I would have to wear my seatbelt. So I just assumed that my dad visiting his inlaws meant he was going to visit our relatives who lived where there was a seatbelt law.
