First time riding a PWC was 4th of July weekend on Harding Lake in 1988.
The local DOO dealer had just gotten in two 1988 Sea-Doos and they were letting people demo ride one of them (the other got stolen). I took to it like a fish to water.
Summers are short up here, hot days are rare but for the first time in my life I was playing on the water. I had never been water skiing, tubing, in a lake boat or anything other than a sled, in the cold, on the frozen water. It wasn't just a "first" ride, it was an entirely new world of realizing motorized fun crossed over onto the water when it was liquid.
The money wasn't there to buy one, but I was hooked. Two years later I went to work for the same dealer, as a mechanic, and spent the next 4 summers working on Sea-Doos and loving every minute of it.
