The nighttime activities made me think of this one!
Did you ever play night games/street games as a kid? The kids in our neighborhood would run around knocking on doors after the sun went down yelling about how they were gonna play Kick the Can, Ghosts in the Graveyard, Sardines or Flashlight tag and others that I can't remember. After we played for a while we'd all end up sitting on someone's lawn talking or telling scary stories until our parents came looking for us and we all had to scatter.
Utahns can't be the only ones who did this.
