The AFS motto "Walk Together, Talk Together" is taken from the ancient Sanskrit proverb
Walk together, talk together,
all ye peoples of the earth;
then and only then
shall ye have peace.
It was used in AFS publications as early as 1952 and widely used in the 1960s. There were several songs.
From Rednecks to Red China is a collection of anecdotes related to my stay in Beijing in 1986, which I started to write in the late 90's. I was fortunate enough to be part of a brand new AFS programme with China, sixteen years after my year in high-school in Texas.
