Easy question for me. I'd definately be one at Disney World than Six Flags which is simply because I have been to Disney World a lot and know it well, while I have never been to a Six Flags before.
Here is an interesting question I ask only because I can't decide myself. (My sneaky way of getting someone's opinion.)
If you were a sharptooth Chomper's age, would you rather live on insects or other dinosaurs?
Consider that dinosaurs must taste a lot better, but it would be much more difficult to make friends with leaf eaters if you ate their kind, considering that most flat teeth would reject the importance of the fact that sharpteeth balance the world by doing so.
