It is the very first foreign country I have visited. I was taken there by my mother, on her numerous trips along with my grandfather and pretty much all the siblings and the neighbours we knew.
The year was 1990 and I haven't been there since. Back then, it still stood as Yugoslavia, although I only visited present region called Vojvodina, which is still part of Serbia. For the sake of accuracy and for not knowing precisely what dates we've been in each city, this is a list of all dates in the passport for the serbian trips: April 10,16 + May 13,21 + June 8,9,12,16,25,28 and August 17 of the year 1990.
Places I've seen are: Subotica, Zrenjanin, Senta & Kikinda.
