OK, so this is cool and all. As are the other palces mentioned above, but dude, This Place totally one-ups all of them, because at the Virginia Safari Park, not only do you drive through all the animals, you get to feed them from the safety of your car. No rules about keeping windows down and all that.
Some examples of people feeding llamas and camels and zebras poking their heads in your front window, are enough to convince you that you need to go visit Virginia.
Having gone to this wondrous land of enchantment, I now have wonderful visions of a llama sneezing in my dad's face. And that is the kind of memory you can enjoy forever!
True, the Virginia Safari Park doesn't have lions, but as you so succinctly put it, lions at zoos are generally lazy and useless, and you'll get much better views simply by watching Lion King again.
EDIT: Llamas are cunning animals. They have learned that they only get food from cars that stop, and that cars only stay on the road of the park, so they have developed the wonderful tactic of blocking the road until you stop moving and THEN walking up to your window on the side of the car. Also, Bactrian camels know better than to try to eat food out of the bucket while it's in your hand. Simple solution: "bite the bucket, and then those Jatravartid humans will let go and I'll get to eat the whole thing!"
