Primarily the outer balls at Copper and the outer balls at Monkey Point. One time we were swimming with a mother/calf. My son let out a "hey Mom, I just petted it!!!" At the time we were amazed and thought it was really cool. Then reality set in after doing a google search. REALLY DUMB IDEA!!! Apparently the mother does not like this at all. There are numerous cases of shattered pelvic bones where the mother rams the offender with her head.
Oh, and a really dumb idea learned after the fact, don't swim in fish balls. Pelicans can really F you up.
