So it's totally possible to turn Sanok or Nowy Sąncz into big cities.
What for? If it hasn`t happened so far, it means there was no need for that.
And why not - they're much closer to the core Central Europe (Vienna, Bratislava, Budapest).
With today`s opportunities in transport and travel, several dozen kilometres more or less mean nothing. Krakow is about 70 km from Nowy Sącz straighline. What difference does it make to reach the core of Central Europe from the area?
It's Lodz, Poznan, Bialystock and Lublin they're fairly isolated, away from important foreign cities.
Poznań isolated? I thought 3 hours from Poznan to Berlin by car on a highway is quite short.
