Two Day Rave Sponsored By Park Does Dolphin In:

Seven dolphins dead in three years at that park? That doesn't sound like a park that should be allowed to keep such sensitive creatures. Somebody needs to step in and take control before more animals die.

Seven dolphins dead in three years at that park?

Not to defend the obviously incompetency of the park in some respects, but since dolphins typically live to about 30- or 40-years in captivity, and these shows reached their highest popularity in the '70s and '80s, many of these animals could have died from old age.
