In 1994 I was in Sana’a in Yemen when two things happened: war broke out and I met Bruce. I’m not sure which of these two events was the more significant for me, but I suspect it was meeting Bruce. Long long ago, before the internet began, a traveller sitting in a hotel room in a new place searched the index of guidebook, but failing to find any mention of the area, was forced to go outside and explore, even to talk to people. There was no phone to reach out and consult. What on earth did we do with our hands in those days? Write in notebooks?
