My first time was in Cancun doing a discover scuba class. I did about an hour in the pool learning the basics. My wife tried too but couldn't get comfortable so she skipped the open water dive. Then that afternoon I got on a boat and headed out to dive. Max depth was 30ft, but it was open ocean so I was a bit nervous. All I really remember was following the fins of the instructor in front of me. After that dive I didn't find it too fun because I was nervous. I didn't really think much more about diving. The next year we went to Cozumel and we spent the day at a beach club south of Cozumel palace. They had scuba diving and discover scuba there so I thought I would give it another try on a whim. This time it was just me and the instructor. I had my digital camera in a housing and he saw that so he picked out things for me to shoot. I saw eels, lobster, octopus, large tarpin. We even did a swim through of a fairly big overhang. It was amazing. We ended up going back to that beach club later in our trip and I did the same discover dive again. I was hooked. I told my wife next time we gear near warm water I want to be certified.
Last summer we were going on a cruise with her family so I got certified in a quarry in PA. It was cold and dark but I suffered through so I could get certified. After certification I went back to the quarry a couple of times before my trip. I began to like the cold dark water. I never though I would. Now I live in Indiana and dive a drysuit and keep diving year round. I have been diving every month since I got certified no mater the temperature.
As long as I'm underwater and I'm still breathing I am happy.
