Aside: It struck me last night that Istanbul was the world's first major international city. Think about it. The Silk Road begins (or ends?) here. This is where East meets West -- for real. Greece, the Balkans, and Europe to the west/northwest, the Middle East and Africa to the south, Persia (Iran) to the southeast, Georgia, Azerbaijan, and Armenia to the east, Russia and Ukraine just across the Black Sea ... this is where it all comes together, now as it has done for centuries. If any city should be used to multiple cultures, it's this one.
That's my report for today. Not sure yet what the plans are for tomorrow. Maybe we'll go to Asia, or to the Grand Bazaar, or something else entirely! Come back again and find out. :)
