Shrinking Cities

I came across an interesting article on the BikeCalgary site.  It's a good read.  With over half the global population living in cities, it's worth looking at how big they can be vs. how big they should be.  It's also about scale, specicifically human scale vs. car scale.  A quote from the article:

Buildings would, on average, be higher, houses would be replaced by apartments and cars by bicycles, walkable streets, streetcars, and elevators. Pleasurable and beautiful places like rooftop gardens and restaurants, multi-story solar greenhouses and bridges with spectacular views connecting buildings would predominate...

Sounds like a nice place to visit, and I'd want to live there.
