One of the things I appreciate greatly about living in a Finnish "concrete suburb" (a decades old, concrete-walled apartment complex) is that actual nature is always a 5 minute walk away in every direction. I can walk from my living room to deep in the quiet of the forest faster than I can listen to the median Dream Theater song.

I have to say I like this much better than lawns, or frankly having a yard at all, although actually owning a patch of forest someday would be the ideal.
