I used to dive, but moved north several years ago. I used to dive six days a week, have dived in every ocean except Indian and Arctic. Scuba diving is the absolute most beautiful experience anyone can ever have. Nothing compares to the majestic beauty of the underwater world. Anyone who loves animals and the natural world will do themselves a great favor to try scuba and dive several times.
When I was a kid, I liked to watch the Jacques Cousteau documentaries. They were beautifully filmed and very popular. But actually being in the water and seeing what is there is far, far more beautiful than any film or photo can be.
I also did some freshwater diving, including under the ice. The light and color under the ice is beautiful, like nothing else I have seen. Sort of like a natural beautiful cathedral.
Why did you ask about diving? Is there something you want to know?
