I’m back in New York and wanted to drop you a short note to thank you very much for organizing my trip and arranging for Tarek to be my guide — he has an encyclopedic knowledge of the ancient sites, and also of current events, so it was a joy to spend a few days with him. I’m really glad that I was able to visit Libya during its period of transition and look forward to returning in a few years to see the benefits of this change.
