This is a notice board in Georgia near Turkey border. (Sarp border gate)
This made me laugh, they wish good luck to people who is going to Turkey.
Maybe they're right :)
Tarlabasi, is a very interesting district of Istanbul. But, unfortunately it is not safe to walk there. I'm planning to drive to there one day with scooter. Sulukule district also is in my list.
In old times, like 19th century, these were very rich countries, their residents were jews, greeks and armenians. So the buildings are very beautfull. After, all these people left these buildings alone (because of politics; search greek&turk relation between 1919-1960) and generally gitanes comes in place of them.
