Very interesting, thanks for the link Mark!

Personally, I'd be perfectly happy if, in some alternate reality, Portland never built another tower over 20 stories but instead was able to rapidly densify the central city over the next decade with well-designed mid-rise mixed-use/residential buildings. Hell, we might even be talking about a legit CBD subway, not to mention a very lively 24-7 streetscape and cultural atmosphere.
