Has the public provided you income?
I suggest you travel to Berlin Germany to experience a truly great city.
When in Germany, check out the Nürburgring racetrack for a racing experience like no other.
I have not been to all of the German cities but have been where I suggest. Like the huge stadium at Nuremberg where they had the trials after WW2. That stadium will floor you.
I missed in Nuremberg the site of the trials but imagine the rest of the city is also excellent.
Places I wish I visited, Munich, Berchtesgaden, and Hamburg. Stuttgart is also magnificent.
