The Road to Hell

It may be paved with good intentions, but it also has attractions:

1) The San Diego Wild Animal Park
2) The San Diego Zoo
3) Sea World
4) Disneyland

...

1) Confined animals in a simulated habitat, still sort of acting like animals.
2) Animals in cages, not really behaving like animals.
3) Animals trained to perform tricks on command. Totally not animals.
4) "Animals" wearing pants.
