So time for a story.
In 1983, I still had the one that came out in 1980, or '81. I was eighteen now, and some friends and I were going to meet up with some other friends to go to 'the dam' and launch some simple fireworks for the Fourth of July. Now, fireworks are illegal in the state of N.C., so of course, everyone went to either Virginia or South Carolina to get them. (We were closer to VA.) They had gotten several good ones to launch and we were looking forward to it. Well, we got word that some of the gang had already gone to the dam ahead of us. We were miffed (not really) and decided to play a practical joke on them.
That circuit box could create a siren sound. My car had a CB radio (dating myself here) with a PA horn attached. So, I wired the box up to create the sound, we grabbed a few blinking lights that we could attach to the car, and we drove to the dam. We arrived and saw that they were out there firing off a few things. We waited for a minute, then suddenly floored the car and hit the lights and siren. We blasted onto the dam (which had a path for driving over it. It was an earthen dam, and it was more to create the lake than to dam up the creek) with the lights and siren blaring.
Well, the crew on the dam exploded in every direction. Our buddy Nick actually ran and dove into the lake to try and swim away! The others just scattered... at least for a moment. Then, they saw that the car coming was a 1978 Chevy Nova instead of a modern police cruiser. Of course, we pulled up and fell out of the car laughing. The crew that was on the dam also started laughing. The lone holdout was Nick, who was not happy that he had tried to escape into the water. We were all adamant that this was on him, as no one else tried to do that, or even thought to do that.
I miss those times.
