I went to Knez Mihailova street walking, and then walked back to my home using another way. It was wonderful. I went to St. Marko Church, which is often called the church of students - because students go there to light candle before exam. It was beautiful experience. Later on I went to book fair in Dom Sindikata. All in all I was walking about 5 hours, and it is good workout. Weather is nice.
