Certainly an odd and interesting place, Selcuk! I am shocked by the casual availability of drugs. And, men without shirts - well, I don't like seeing that here in the U.S. either. On the beach, okay. But, not on the streets.
As for the flag colors being everywhere, we have the same in my city but it's not our national colors that decorate every surface; it's our university's colors of orange and blue. They are everywhere!
