I was diving for Abalone in S.E. Alaska when three sealions came zooming out of nowhere and started swimming broadies around me in tighter and tighter cicles and one of them grabbed my abalone bag. I sure didn't holler at them or throw rocks, it was about all I could do to stay cool. They appeared to enjoy the lunch, and the only thing left was the nylon bag in shreds so I gathered it up and headed for the beach where we belong.
