Need A Little Green Space?

I was thinking the other night about living in Seattle (as I often daydream about), and came to the conclusion that I am a very nature-loving person, and that's what makes Seattle the best place for me. Here's why:

1. Seattle is ridiculously liberal. I've been discouraged to move there by a few conservative friends just because of it. This also contributes to the green-ness of the city. Many ordinances have been passed to keep emissions low and greener activities high.
2. There are trees everywhere. When I visited Seattle, I was shocked to find that, in Pioneer Square (in the middle of Downtown), there's basically a forest. These trees may have been planted to keep people dry from the perpetual rain, but nonetheless, they keep the air nice and clean, which brings us to...
3. I don't get a respiratory infection by taking a few breaths. I had a sore throat and a cough related to the traffic and generally bad environment of the large city (it was worth it!). Seattle, however, smells like rural Missouri. The air is so clean there. I love it.

So I began to wonder if an abundance of parks was a huge factor when considering migrating to an urban area. Parks offer a sense of separation from the bustling city and a calming connection wtih nature.

Take, for instance, Central Park in New York. It's massive. There are 8 million people in New York, all of whom most likely need to escape their everyday muggings (DISCLAIMER: Central Park is actually the site of many rapes per year). I figured that if I ever found the money to live in Manhattan, I would visit Central Park everyday for a nice run.

If you were to ever move to any city, would parks and green space be a huge factor in your consideration? Why or why not?

I know it would be for me.
