Having grown up in the suburbs (with plenty of real woodlands around), I have the exact opposite feeling. The community, diversity, tolerance, and learning opportunities of a dense city are better than any suburb or small town. As far as nature goes, I just went fishing with my son the other day (in an abandoned quarry, funnily enough). My wife, who grew up in the countryside of U.K. feels the same way.

Disclaimer: I live in downtown Chicago.
