Oh Say, Can You See? A Musical Salute

Sunday, January 05, 2014

Some things are so familiar, so fixed in our heads, that we stop noticing them. Buckle-your-seat-belt instructions in an airplane, for example. You don't have to listen. You know the drill.

I'm a fox. It's January. I'm hungry. I want a meal. My food, however, is buried 3 feet down, deep in the snow, hiding. It's alive, in motion, and very small, being a mouse. So how does an above-ground fox catch an underground mouse? Well, the answer is nothing short ...
