Antilocapra Americana

The pronghorn’s not an antelope.
We often call it that, but nope,
It’s closest relatives — don’t laugh —
Include okapi and giraffe,
And all Antilocapridae
Have gone extinct except for they,
Like dinosaurs and low-priced gas.
Try not to scowl as they pass
Your gasping car at 50 per,
White bellies and brown backs a blur
Against the dusty hills they’re roaming
Nigh the byways of Wyoming
And adjacent high plains states,
White tails in place of license plates
And bi-pronged horns that rarely beep:
You’ll catch them next time gas is cheap.
