The Bermuda Triangle game:

In the mid '70s, The Bermuda Triangle was a hot topic. There were several TV specials on the subject. "In Search Of" did an episode on the subject. I really didn't know what it was at the time, and quite frankly I'm still a little vague on the whole thing, but whatever. In '75 they even came out with a game about it. A neighbor had it and I played it once, but mostly we'd just set up the ships on the board and have the cloud devour them. Sometimes I found board games are the most fun when you make up your own rules...
