@clacke @strypey @tbaldauf @Br3nda @AccordionBruce the US have bigger gaps between their cities than China? really? I've been on a two-night train tour within China, and it seemed quite empty between the large cities. but since that was in my teenage years and I had no part in the planning, my perception could be way off.
Not trying to question your statement here, it's just counter-intuitive for me and I'd like to know more.
