This was not a terribly common site, as I grew up... my Mom and Dad totally casually relaxing in the yard to the south of our farm house near Coon Rapid, Iowa. This is late July 1960. This is a couple of months before their first grand-daughter, our daughter, Annette, joined the family. We were visiting the farm, from Ames, where I was between my Junior and Senior year at Iowa State University.
Families are Forever! ;-)
