- What utter hogwash and speculation! Everybody knows it is impossible to
- travel more than 70 miles per hour. Probably not even quite that fast.
- Proof: The cheetah is the fastest known animal to pull the cart. And
- cheetahs are well known to be quite unable to run more than 70 miles per
- hour, even *WITHOUT* a cart.
