WHAT???? I can hear you now ... not really, but I'm sure that's what you said when you read Scuba Diving 101. It was Tuesday. There's not much going on around here on a Tuesday. The wind blew so hard I had no intention of going outside, although I did trek out once to try and find my rubber mats. One was at the bottom of the hill, the other stuck in a palo verde tree.
Cooper wasn't much help in the entertainment department, so I spent the good part of two hours vacuuming my house. I know, shocker, right?
This is your BCD ... buoyancy compensation device. Valves put air in or dump air out of the vest to keep you from rushing to the surface, whereupon you will get nitrogen in your blood and die. It's that simple.
You attend class after class, truthfully learning how to survive (and not drown) under any number of circumstances. There wasn't much mention of the fish or sharks we would be swimming around with in Monterey where our final test would be taken. If you survive Monterey diving, you can dive anywhere in the world with ease.
