My parents would call people they knew depending on the city they were driving through because it wouldn't be long distance (oh yeah here's one, the scumbag phone companies would charge you more when you weren't calling a local number, meaning within the same county/parrish/borough, usually by the minute). They even did this once they had mobile phones! Imagine nowadays contacting someone because you're going through their city. It's like, "Hey, I like you, but not enough to see if we can meet up for a little visit just to say hi all because the phone call is cheaper."
