Well Bushwacker was right again. Just enough to be dangerous.

My thinking about diving in the Keys was how much trouble can we get in under 30 ft?

Turns out quite a bit. Bubbles expand far more under less pressure. If you were to hold your breath and ascend from 30 ft you could easily get an embolism. Not good.

Lesson: Never stop breathing. If things go south, exhale on the way up. From any depth.

Cheers,

I know I am repeating some points, but that is fine.
