Ok, I really have no problems with neighbours. And now Crystal Caverns showed up, I think it was east of my town. Crystal Caverns, I'm sorry if this upsets you in any way, especially as this is my first message to you - but why did you make a big, ugly hole in the middle of the sea, next to my sea town? How am I supposed to make my epic naval docks look nice when there's a big *lack* of sea next to it? It's not even within your city borders!
This is generally to everyone:
Is it only me that think it's just somewhat good form to at least announce/ask if it is ok to make medium to major changes to neutral territory? There's really no point for me to build a naval docks if someone f.x. finds it important and/or cool to build a railroad bridge circumventing my town in spirals through neutral territory towards its remote island. It kinda ruins the view when there's stuff in the way of some reason.
I don't like that people build or harshly terraform outside city territory. It's really not a nice thing to do. I know, I don't own the areas. But you don't either. Treat them nicely.
