Brian's Drive-In is one of my fave websites. I presume he must be my age because he tends to focus on the stars I knew as a boy.
here are a couple of pictures from his site which showd how young men kept in touch in that long-ago time before cell phones.
Rory & Guy
Tab & John
in case you're too young to remember (& if you are get thee to Blockbuster) the first photo is Rory Calhoun & Guy Madison. & on the bottom (did I really say that?) are Tab Hunter (whose autobio is in the works) & John Bromfield.
