I moved to the suburbs about 5 years ago. Since then there has been a sidewalk installed for about all of the two miles from here to the town center. The town center and the road all the way along have been regraded and then repaved with improvements made to stormwater control, there are new crosswalks and other traffic controls, and the shopping center there has also just been repaved.

I am thinking that you have seen what you have seen, but there are 50 or so communities that can each be called a suburb, and they are each in a different place and heading in a different direction. You did not describe the suburb I live in really at all.
