I'm currently in a neighborhood that was empty farmland as far as they eye could see just 5 years ago. I had never seen a building being built before, but now I drive past 4 complexes being built just on my way to the grocery store. They're also building a closer grocery store.
This area is going to be so nice in like 5 years, but right now it's an absolute mess of construction, road widenings, putting utilities in the ground, etc. We didn't even have cell access here when I moved in 9 months ago.
