In 1969 I spent a summer travelling around USA on Greyhound buses; half a century later (to the day) I went back...
I wasn't expecting to write another book. But I was sitting in the dentist's chair when suddenly I realised I was coming up to the golden anniversary of my trip of a lifetime. So I took out the diary I had written at the time, signed up at the gym, bought a smartphone and flew back to New York.
I travelled 6,000 miles, in the course of which I gazed on a now derelict Houston Astrodome, rode (again) with the Pasadena Police, joined young Americans on a climate change protest in Boston, and despaired of the divided politics. As one reviewer of the ensuing book wrote: 'Not just a changed country but a changed narrator'. Details of the book can be found here.
