4th January! A reminder note tells me I travelled to the US on this date, 30 years ago. Hadn’t been before. San Francisco airport, was held up by an official, because visa wasn’t right. Would I be sent straight home? No, but he used this as a training exercise for new recruits. Arrived in Philly, 7am, no-one was expecting me, as they assumed I’d get the date wrong. Happy to say, it got much better after that.
