…when you find out it only costs about $100 to take a train from Katowice, Poland to Vienna, Austria.
And you wonder what it would be like to take a ride down the Danube, or go to Mozart’s house. Browse through books at the Österreichische Nationalbibliothek. Ride the Riesenrad, against your better judgment. (It was constructed in 1897!)
It’s fun to think about, anyway.
