Every so often when I was in high school, some kid would call in a bomb threat and everyone had to evacuate. This was in the early 90s, before most people had cell phones. They would probably do it from the pay phone at the front of the school. They almost certainly were kids from the school trying to get out of a test.
That’s a really stupid thing to do, but I understand why a kid would do it. This I don’t get. Why call schools in another state?
