My mother-in-law's cousin, known to all as Uncle Frank, emigrated to US, having met and married a Wellesley girl in the 20s, and worked a as a science teacher in New Jersey . He used to tell the tale of a bright electronics class he had who made a zapper that would work everone's automatic garage doors and they used to cruise down the streets sending everyone's doors up and down- a sort of modern-day version of the game.
