Helsinki – Stockholm – Jonköping – Uddevalla – Götebörg – Helsingborg – Helsingør – Copenhagen – Roskilde – Køge – Møn – Lolland – Fehrmann – Lübeck – Hamburg – Schwerin – Güstrow – Müritz – Magdeburg – Potsdam – Berlin

I am roughly half way through. I will leave Berlin tomorrow and will head back home via Baltic states. ETA is the end of the month, but I am notoriously bad with estimating arrival times.
