@ossobuco,
The best creative ideas often spring from disagreement - it seems to stir the creative juices.
Cities versus the country - that stirs a lot of mixed emotions in me. I was born in a city, but a city within easy walking distance of the countryside, and only a few short miles to the sea - when I'm in one, I crave the other!
To me, nature can mean the sight of a night sky glimpsed above city streets, or rolling fields, a bunch of weeds growing from an old brick wall in town, or a dramatic waterfall.
