Mama M. I feel the same way. I actually moved to San Diego when I was younger because I wanted to be a dolphin trainer. I love that place, and had a season pass the entire time I lived there. I used to go by myself all the time, and I did work there for a short while (not as a trainer, but as an educator - it didn't pay all that well though).
I am sad too. The entire thing makes me sad. That this persons family now has to deal with his loss is a tragedy. That people now want to euthenize an animal which arguably was just doing what is in it's nature is heart wrenching to me. That Sea World (a place I really do love and that I really do think goes a long way in their conservation efforts) is now under attack makes me want to defend, even though I don't know if I should.
I just wanted to say - I feel you!
