Sure you are right and of course we would love to come back there to see all those things we omitted but as we only have a couple of days you shouldn't be surprised that we want to see a different part of the country.Saying that You've seen Juzni Kucaj by beeing in Lazarev kanjon, it's like saying "i've been to New York, and I have seen north america"
Every corner of those mountains is worth seeing, so it does not really matter if you covered one, or more areas, as long as you have fun
Support car is very comfortable thing but first: we do not have an extra person to drive it, second: it decreases the challenge, which is something we are looking for.
For me Stara Planina is a must. I will wait patiently for the proposal from Aleksander (there is no hurry - we have plenty of time ) I guess then we will go south as long as possible, even continue the trip in Macedonia if we manage. Another idea is to start in Bulgaria (they have Stara Planina too) and then get to Serbia. We will see.
Is it really dangerous to leave the car in the street or a public parking place?
