Quoted from book:
In October 1972, our family and other members of a food-purchasing collective, Farmers Feed Hams, put on a melodrama, "The Saga of Spanishtown Sue", in which Anna portrayed a daisy growing in a garden. The production was notable for several reasons. The play epitomized our innocent, cheerful life in Purisima Canyon. Under the guise of comedy, it dealt with a number of opinions regarding landlords, religion and morality. The primary theme, however, was child abduction, a subject we never thought to deal with in real life.
Was this play open to the public? Just a thought, is it possible the couple in the car noticed Anna on stage? Would anyone notice if GW was in the audience? I doubt he would have been there, not wanting to be in her life at all. I'm sure she was as cute as a button!
