Each dive site has its own attractions. Even if you don't live close to the ocean, diving is great fun. Diving is as close to being in space as you will ever get without going there. You are in a different world and have to learn special skills to get there. You will see things that are completely different from anything you've ever seen before.
Diving is exciting, thrilling, calming and relaxing all at the same time.
It is a great chance to commune with nature and explore your own limits. Water and the things in it absorb light. The deeper you go, the darker it gets. In some places, however, where the water is very clear, you won't notice any difference at 100 feet from what you could see at the surface. Places where the water isn't as clear, the water gets dark quicker.
