ragdoll: More on Little America

From Roadside America:

“Little America—well-known to I-80 travelers as The World’s Largest Gas Station—was named after Admiral Byrd’s camp on the South Pole. Opened in 1932 by S.M. Covey, the refueling stop along the Lincoln Highway grew to include scores of gas pumps, a hotel, restaurants and a post office.”

And on the penguin whose name is Emperor:

“Emperor’s glass case is inviolable; you’ll never see this bird wearing a Santa’s cap or a New Year’s diaper. In the words of one Little America employee: ‘The management doesn’t allow joviality with the penguin.’”

I thought the I-80 Truck Stop in Davenport, Iowa was the world’s largest gas station. Or is it the world’s largest truck stop? In that case, what’s the difference?
