Awesome! I did my first dive as well in1972 but only got the ‘resort’ course certificate. We lived in Antiguan at the time so was still able to do lots of dives before becoming NAUI certified.Welcome! Well Seasoned Diver here. First dive in 1972.
What’s interesting is the number of folks like ourselves who took up diving at an early age and still do it in some capacity or the other. I guess this is what defines us.
