Congrats on your first official dive. Sounds like you had a great time. My son was 14 when he got his cert, our first dive was memorable but in a bad way, some heavy surf built up after we entered and we took a beating crawling up the rocks which was the only way out. Our 2nd and 3rd dives were awesome, went on a cruise and dove in the Bahamas. Made up for the first one. He still reminds me of that first dive. Dive safe!
