Drive from Prague to Vienna
It took me about 5 hours to drive from Prague to Vienna, instead of about 4, because I wanted to stop at a pinball place that supposedly has 142 pinball machines (according to Pinball Map.)
Unfortunately (but also fortunately in another way), it was closed, which was good, because I got to Vienna by 4 PM, enough time to drop off the car at the rental place (EuropCar is pretty reasonable compared to the big companies.) There was a booze and other stuff (cigarettes, toys, etc.) shop at Excalibur, so I loaded up 5 bottles of booze.
