I travelled to the Soviet Union in 1990. Georgia was part of the tour and Tblisi was my favourite city to visit, as the people were warm and friendly. We had also been to the hectic city of Moscow beforehand and the slower, peaceful pace of Tblisi was a welcome change. I don't remember much about Mtskheta but I have pictures of the site to prove I was there. But I do remember eating some wonderful hot bread (similar to a baguette) after the tour!
