Where I live, it is law to have about 30% of all land to be dedicated to open space and parks. It keeps congestion at bay, though it does raise the cost of housing to obscene levels.
This was taken during an early morning hike, and looking back on the trail, I saw this. It rather epitomizes what California once looked like, not all urban sprawl and gnarled freeways.

A cool law and love the building in the landscape.
