Mysteries in the sky

It was just before 5 p.m. and I was driving west on Highway 20 with the grandkids in the back seat. We were on our way to Iowa Falls and took the Eldora/Steamboat Rock exit and turned north, which put us on Highway S56. We traveled through Cleves and continued north toward Ackley where normally, we would turn west onto 120th Street about a mile before Ackley, and then travel west on D15 into Iowa Falls.
