I read many years ago that AUH2O was his vanity license plate. Dunno if it’s true.
AUH20 license plate: true enough. I remember pics of it. I always was a Goldwater guy. My copy of his book “Conscience of a Conservative” is from 1963 and that’s not even 1st edition. The only thing I disagreed with him about was claiming the political “right” for conservatism. I thot he should have claimed dead center. In my view, at least, conservatism stands for long term stability, not stick-in-the-mud status quo.
