I don't think noticing nature is so much of where you are as it is what kind of person you are... You can notice nature in the city almost as much as anywhere else - you just have to work harder. (Or be grateful for the starlings, sparrows and squirrels - as children are.)
I am grateful for all the bits of nature I can see wherever I am. I love seeing the differences between the Pacific Northwest, (where I grew up), the Upper Midwest (where I came of age). the Northeast (where I became a mother), Britain (where I lived many years and have left a significant chunk of my heart), and the Rockies (where I am now.)
However, I am definitely not a city girl and feel claustrophobic with lots and lots of people (and their auras) too close to me. I'm in a city of only 50,000 right now and that's about as large as I ever want to experience again, to be perfectly honest. I'd still rather live on the outskirts of one of the outlying towns though. I'd rather live in a village where you can walk to everything - including getting out into nature more!
I guess that is what it all about . being grateful or appreciate what we have to make the best of it .
