I want to track down and befriend this Kevin. His question made me laugh so hard it gave me an asthma attack. But it's bothering me that I can't pin down the reasons I find it so funny.
I guess it's mostly the extreme unlikelihood that the OP would confuse her daughter with any other child, let alone an animal, let alone a *bison*, let alone an inanimate geographical space, let alone a space full of (of all things) bison... and the fact that he asks the question despite its utter superfluousness. I remain unsatisfied; I feel there are other reasons I'm not perceiving.
