CORRECTIONS
- Now I regret mentioning the Danube river! Apart from that one aside about international diplomacy and a port: for the rest of the networks I did not include rivers, even if they are navigable to an ocean. I appreciate these would change things like London and apparently the USA has some super great lakes.
- Let me know if you spot anything else!

Happy birthday to Eliyahu!
