Dave Crosby was a Serious Diver

Before he died in January, rock legend Dave Crosby told Stephen Frink, for a 2013 interview in Alert Diver magazine, "I grew up in Santa Barbara as a kid, and I would spend all day, every day at the beach. I was sailing that water by the time I was 11, and now, 60 years later, I'm still at it - either sailing on it or diving under it.

"You can't be around the ocean and not notice things are changing. Drift nets are a shit show ... 30 miles of line that kills anything that swims in its path. Global warming and ocean acidification are massive challenges to the sea. And to mankind, for that matter. I find diving the most peaceful thing I do in life, but as divers, we need to be fighters. The ocean is so elevating to my spirit I am willing to fight for it."
