I have a plan to see all the places worth visiting in my country first, and then move on to other countries in the region and later European cities. For now I only have a couple places in my country I haven't been to, but I hope to visit them this summer. Than it's probably Belgrade and Sarajevo (already been to but I wanna go again), Dubrovnik in Croatia, Ohrid in Macedonia, Greece, and so on. From countries abroad, I've already been to Italy (all major cities) and Russia (Moscow and St. Petersburg).
