We started from Tbilisi. Then drove by the military road to Kazbegi and back. Then we drove to Batumi, visiting Kutaisi and other cities by the road. After spending couple days in Batumi we got back to Tbilisi. I assume, you had very similar route.

I still don't understand how kids go to School in Tbilisi: it's barely possible to cross a road with all these maniacs and useless "zebras".
