On any Saturday or Sunday morning in the neuralgic spots of the city you see this image which is becoming more and more frequent as the flow of tourists grow beyond expectations. A huge number of people standing in line waiting for the Bus Turistic to come. I was waiting in front of the Triangle for my wife, and took my camera and shot at the innocent victims (not mine) suffocating under the morning sun.
