Tara

My encounter with Serbian people has left a very positive impression so far, and this hasn't changed after visiting the country. We didn't see much of Tara itself (where the conference was), but I saw the largest amount of snow there so far this year. 

Belgrade

Belgrade has polluted air (which can be smelled as soon as you walk outside), traces from past wars and bombings, lots of people sitting in front of a freezer selling icecream in the middle of the street, lots of meat, lots of air conditioners on the outside wall of the buildings, and lots of amazing bookshops (and not all books are in Serbian).
