Doctors are taught that when you hear the sound of hoofbeats, think horses not zebras. It’s a saying I’ve always appreciated, worrier that I am, a reminder to see the molehill instead of the mountain. But even doctors know that in some situations, it’s better to think mountains — or zebras.

This is especially true in Maryland, where five zebras escaped from a farm and 30 days later have yet to be caught. Zebras have been spotted grazing in suburban yards and dashing across suburban lanes. 

Officials tell folks to be careful around the wild animals, that they cannot be caught, they must be corralled. Funny, I was just reading about zebras in the book Guns, Germs and Steel (more on this classic in a later post), how, unlike the forerunners of the horse, zebras are impossible to tame. They cannot be lassoed, and they have a tendency to bite. 

The Maryland zebras are living proof of these biological and historical facts.
