Once, while skiing in Gudauri, we got snowed in (cut off from Vladikavkaz and Tbilisi) and we were trying to figure out how to escape the white wilderness – we looked for different options (we had plenty of time), and eventually found a bunch of cars on BlaBlaCar, with guys from Tula, and that's how we managed to get out of there. So, I would suggest not excluding BlaBlaCar, the traffic on that road is really high, as people are traveling to Armenia and Baku.
