Wow ... "What I Love About SCUBA" is a book I haven't finished writing yet, but it will be lengthy! There is no quick and easy answer to that question. I used to say "wrecks" ... but I've come to realize that one of the biggest appeals for me is the sensation ... the feeling of hovering, the feeling of the water around me ... the serenity ... the sensation you get hovering beside a huge structure like a wreck or a wall in awesome viz, that sense of scale ... that really opens my valves, if you know what I mean! Plus all the other stuff too: the adventure, the challenge, the beauty, the mission, the freedom ... whew, I could go on and on!
