Dear Graham,
This is the river Danube which runs through Budapest. The city on the side of the river nearest you is Pest. The city on the other side is Buda. Hence Buda-Pest. I haven’t had time to look at the place, and I am now out at the airport spending Hungarian forints (that’s the name of their money) as fast as I can because they are of no further use to me. Lots of love to you & Trellie. I am off to Bucharest.
Love dad.
