In 1935, my paternal Grandparents built a little travel trailer and towed it from Oklahoma to Wash DC with their four sons (my father being the oldest). There they learned that they were of the 'Jonadab' class. I heard the story told my whole life. Grandma looked at Grandad at some point in the program and said, "Oh! We're Jonadabs !". This seemed to tickle the you know what out of them and they went back to Oklahoma with renewed enthusiasm.
Shortly before he died in 1969 my Grandfather told Dad, "If this 1975 deal doesn't work out I'm going to take another look at this whole thing."
