Here is a short clip to illustrate what kind of roads you might hit in baltic countries

For the Baltic countries I used a map with a scale of 1:400000 - the roads marked with white were typically dusty gravel roads and sometimes caused some smaller surprises.
The streets marked in yellow and orange typically caused biggest surprises. Their quality ranged from totally horrible i.e. bumpy, holes in the street, borderline asphalt/gravel might have high edges to brand new and smooth.
Generally the streets we rode in Latvia and Lithuania were the worst. The front suspension on my sidecar needed adjustment. The bike/helmet camera quit its services most of the times on those roads and that's why I do not have clips from there.
Most "interesting" are those roads which have asphalt in the centre and gravel left and right. Typically both are in bad condition with the gravel given an opportunity of even bigger potholes compared to the asphalt. As everybody wants to ride the middle part as much as possible, here seems to be some way to "play chicken" with the traffic coming from opposite direction.
And even though you think you go fast - maybe we rode at about 90km/h, watch the mirrors for the local heroes
