I can see what you mean. I lived in the same town for the first couple of decades of my life. It's satisfying to know people in the town and point out who owns what building because I polished jewelry for him at his store in high school or which restaurant real estate is cursed because I've seen a dozen places go in and out since middle school.

But moving to a new town can teach you how to insinuate yourself along with a certain community (business perhaps) in a new town and know what the score is by making new connections.
