security, freedom, being affordable ≧◠◡◠≦✌
Just the people in general. Size of the city isn't very important, decent enough nightlife.
Anything that is important to you.
Its not about what I think.... its about what the person who wants to move thinks.
People move for a reason. That reason is what is most important. For some, it might be a job.... for others to be close to family.... for others to run from a bad marriage ......etc. The most important thing to look for is what satisfies their need to move. Personally, I'm happy where I am. I have no reason to move.
