My grandfather was a cryptographer. He used to send me letters in code that I had to break before I could read them. I recently found his old notebook and some newsletters and info from the ACA. I've had his basic cryptanalysis book for years. His code name was The Squire. A favorite activity was trying to break the code of his latest letter so I could see what he said.
Think of a favorite childhood sport, game, or activity. Make a nostalgic photo today. (@muffett68)
