Seriously?

Entry 1 on my trip with my Dad to the Black Hills of South Dakota. We left Chicago around 1:30 and drove to Iowa and encountered this exchange in Iowa...

We're travelling in my Dad's cherry red corvette convertible... My Dad: "So why aren't there any hotel rooms in town tonight?"

Motel Employee: "Because it's Tuesday night in Des Moines (Iowa) silly..."

Are you kidding me?
