As I remember it, Halloween in Pittsburg had two distinct parts. There was Halloween, and there was Devil's Night.
On Halloween, only children Trick or Treated. But teenagers didn’t mind. We had chosen tricks the night before instead.
The night before was Devil’s Night, and the evening's activities basically consisted of three things. Most common was ringing doorbells, running, and then hiding in a safe spot to watch an adult answer the door with no one there. Soaping windows was also on the list. Particularly car windows. It was always a good night to park the car in the garage. For the more advanced Devil’s Nighter, people would find where a dog had done its business, put it in a paper bag, ring a doorbell, and then light the bag on fire. Adults were supposed stamp it out, but in reality most adults were wise to the trick.
For the oldest teenagers , their role was to discourage the Devil’s Nighters. It would mean hiding in the bushes waiting for someone to ring your doorbell and then giving them chase. You didn’t actually want to catch them; the point was just to give them a good scare thinking you might. Same thing with soaping windows. You’d hide in the bushes, and then when someone just pressed a bar of soap to the window, you’d jump out and yell, “HEY YOU KIDS!!!” They, of course, would bolt like they had seen the Devil himself, which was half the fun of it for both parties.
Interestingly, I don’t recall folks throwing eggs. I think that was regarded as a genuinely delinquent thing to do.
The next day parents would glare at the young teenagers, but then give a little smile when they had walked past. In a strange way, it had the effect of reinforcing right and wrong, of strengthening the limits of what was and what wasn’t appropriate behavior. In retrospect, it was a good natured nature way of teaching kids what it means to grow up.
