Lets see.... way back when GM was 10 years into aquiring dives I was just learning to swim. Not long after that snorkeling was introduced to me... then about 1982 I was given a tank that had straps stuck to it, and what I now know to be a regulator and first stage and told "Go clean the boat... if you run out of air, come up!" - oh, I also had 16# of lead on a belt that I used to snorkel and swim with regularly. After I got married, my wife told me she wasn't going to fill my tanks and we dive... I had to get certed, sooo... I got certed... Funny thing, I had to learn to dive with all the extra gear. Anyway, after getting past that you can see where its taken me
