Roger that jsmith, well said.
Maybe you're right. Maybe it's time they do away with the killer whales, change their logo to a dolphin or turtle, and just repurpose those tanks for something else. I can think of one completely awesome thing to do with that tank if they ever felt the need to build a new attraction.
Anyone ever remember MarineWorld in the late 70's, early 80's? They had that attraction where you rent a wetsuit and snorkel through an artificial reef? I'd love to see a park make one of those again someday. Of all the park attractions that died and never came back ( at any theme park ) that one still ranks #1 in my book. Someone should have redone that by now.
