My one career goal in life was to train ocean mammals (all kinds but really prefered the dolphins). My parents couldn't pay for out of state tuition, I didn't have the grades for a scholarship, so I looked at the Navy because they had a great program even though it was defense oriented. After much research, I realized I couldn't do it. There was so much training involved in explosives and warfare before I could even apply to work with the dolphins that I knew I wouldn't (wouldn't even want to) make it. Here is a site I found recently...I still like to dream.
