Back in the 1950s, Joan Williams' father took her two older brothers on what he called a "nature drive."

The boys were about 6 and 7 at the time. And the backroads route was out in the country north of Davenport.

They soon encountered wildlife of a sort.

"They came around a bend in the road to find a parked car partly blocking the road and there, right out in the open, was a couple engaged in the birds and the bees on a blanket -- in plain sight."

The boys had plenty of questions.

"For years later, my folks would laugh whenever someone referred to a nature walk."
