Balkans (Bosnia to Romania), 14-Oct to 4-Nov

I'm a 25yo Kiwi that's flying into Tuzla in Bosnia-Herzegovina on the 14th of October and flying out of Cluj-Napoca in Transylvania, Romania on the 4th of November. Planning to travel between the two by land, and looking for travel companions.

I won't make it to all (or even most) of these places, but possible stops include Banja Luka, Bihac, Zenica, Srebrenica, Gorazde, Sarajevo, Mostar, Medugorje, Ploce, Dubrovnik, Herceg Novi, Podgorica, Budva, Shkoder, Tirana, Ohrid, Pristina, Skopje, Sofia, Bucharest, Tiraspol, Chisinau or anywhere else I may end up.

Happy to travel by car, train, bus, ferry, plane, etc. Would consider hitchhiking as well. Will be doing Athens to Thessaloniki on the 10th-15th of November as well.

I'm looking for travel companions for all or part of this trip, as well as any locals that'd be keen to join me. Also looking for more travel advice.
