I think it's evident that expensive neighborhoods in Seattle are surrounded by natural beauty. That elevates city life. So if we can make cities more attractive in the long run, we can be smarter about issues like development, zoning and economics.
It would be great to take one city street and turn it into a pedestrian corridor and see what kind of effect it has on the businesses in that area - It's the future I think.
I've seen neighborhoods that I would have never driven though because I'm riding my bike, because I'm looking for side roads, looking for maybe more hills or less hills depending if I'm exercising or not. You see a lot more, and you get the flow of a city a lot more.
If you have a lot of nature in your city, it becomes a more enjoyable place. That's my own feeling about it.
I think ultimately, bringing more nature back into the city is a way to deal with urban sprawl and things like that. If the cities feel a little more natural, people like to live there more rather than moving out and dividing up another piece of land that shouldn't be touched.
