On Sunday, October 28, 2007, Ayşe and I took the bus from Ankara to Istanbul. We picked up Sasha at the airport and took a dolmuş to Taksim. On Monday, Sasha and Ayşe had a meeting concerning the Nesin Mathematics Village. Otherwise we wandered around town, and I took mainly architectural photos. It was a national holiday, Republic Day. That night we took a train back to Ankara.
