A muttered rumble was heard from the pen, and I, in my walking stopped to look in. What was this I saw? A massive beast, hoofed, and jawed. With spikes upon its mighty brow, I watched as he struck the turf and prowled. And yet for all of his magnificence, he couldn't get out of that wooden fence.
I fly, yet I have no wings. I cry, yet I have no eyes. Darkness follows me. Lower light I never see.

They are many and one, they wave and they drum, Used to cover a state, they go with you everywhere.
