Probably a bad spot at the gas station on the highway, cars can't slow down and almost no traffic at the gas station. After 10 min a guy going to Kjustendil gave us a lift and drove us to the border to North Macedonia
A lot of traffic in all directions going through Prrenjas. A couple picked us up (drove a Taxi from Tirana, but without the sign) and took us to Tirana.
We were hitchhiking as a couple an made a sign in Cyrillic with Sofia. Most drivers that go from Plowdiw to Sofia take that road to get to the highway. Took us 15 min to get a ride. Cars slow down due to the roundabout and can stop in the bus lane afterwards
