What's a good city to settle in once you've became successful
Once you've got enough money to purchase a mansion,high class cars etc.
Successful and rich are two different things. You can be a successful person and not be rich. That's a side note and different discussion.
I get what you are saying, if you become filthy rich, where would you live? I mean, whether I invented a fully functional fart filter, found the cure for cancer, or something that would earn me a lot of money, I would buy a small mountain in Vermont or New Hampshire and build a house on top of it. Why?
1. Rock is solid. I don't have to worry about sinkholes of Florida, mudslides in California or earthquakes. I would have to deal with snowstorms.
2. I would have a full view of everything below so security would be much easier.
3. Don't have to deal with ghetto neighbors asking me for a cup of brown sugar. It's like go buy your own sugar.
