Not sure it's just me, but I'm curious as to what state the posters live in as I have no clue where anyone lives. I'm interested in knowing where this growth is happening. I live in a close-in suburb of NYC so there has been very little open land around here for a long time.
The US population has increased by 100,000,000 just in the last 30 years, the bulk of it made up by immigration. For me, I'd be happier with slower population growth.
The growth in 10 years in the area of Colorado Springs by 250,000, yikes, way too many people.
