Sunbathing woman in bikini, August 1969

A picture of a woman in a bikini laying on a towel on the grass in the sun.

This picture was taken on Kodachrome film in August of 1969. There is another towel next to her on the grass and, since she is wearing a wedding ring, I assume this towel was occupied by her husband who has stood up to take this picture. Next to her on the other side are some rocks which could be naturally occurring or could be part of the edging of a lawn, so it's difficult to infer a location from them. In fact it is just about impossible to find the location of this picture now.
