"Shit hit the fan" is actually associated with Detroit, according to the map.

While I encourage the effort, I think - perhaps - he needs a (several) proofreader(s) from the US - and other countries - to tweak it just right.

In the meantime, I would highly recommend Dorlinh, Newman and Sarford's exceptionally interesting "Maps of the World" instead.

But, great effort - and so true about DC!
