I enjoyed both, loved the storms in Russia and the calmness in Lithuania. I have been to Westerplatte on the Vistula River where the Germans landed in 1939 and also to Gdansk the city, I loved the shipyards and the history, but found the city centre to be a bit boring. The city was flattened during WW2 so the buildings though they look old are mostly rebuilt from the 50's onwards.
Looking at the map I see it but not been there
