COMMENT OF THE DAY: WESTERN AIR “. . . in cities old enough to predate water systems it was common for the favored side to grow upstream. Even after city sanitation, flood control, and car ownership that makes it possible to live ‘way up a hill without having to have the leisure to live so far from things – and even where that legacy doesn’t hold over in property investment – air quality is generally better higher up, nevermind views: so that in North America, where our water often flows to the east and south, even newer cities often favor west and north. Especially north. Nashville, Monterrey, East Bay, Memphis, and others where the east or south is higher ground, or cities where race riots took place after city sanitation came around, prove the rule by suggesting how much it takes to buck it and confirming why. Think about it and see why else you can come up with!” [Austin, commenting on Comment of the Day: The Common Divide]
