The only thing worse than boring everyone with the pictures of your vacation is droning on and on about all the wise conclusions you drew from 72 hours in another city. It takes years to understand a place like the natives, and that goes for Richfield as well as Rome.
On the other hand, snap judgments have their place. Sometimes you conclude that a city is messy and unfriendly because it is. Sometimes you love a city's color and charm because it's colorful and charming. It's unwise to conclude that your brief impressions are the whole story. If someone came to Minneapolis in January they'd say it's cold and monochromatic, and they'd be correct — but that would only be part of the truth.
Now that I've dispensed with the caveats, here's why Minneapolis needs a little more Paris and a lot more London, based on my summer vacation.
Paris is beautiful, because it was commanded to be beautiful. Napoleon III ordered up a pretty city, and he got one.
In the middle of the 19th century, Paris was a ragged warren of cramped streets and tenements, ridden with poverty and disease. Just as in the urban renewal movement in the postwar years in America, Napoleon decided to mow it down and build anew.
He hired Georges-Eugene Haussmann, a fellow who'd studied law and music before settling down into a civil service career. Napoleon put a map of Paris on the wall and drew thick blue lines where the new boulevards should go. Haussmann made it happen, and gave the new streets a distinctive look that relied on a lack of distinction. The same colored stone. The same style of ornamentation, block after block. Everything was the same height.
You don't need to understand much French to grasp what Napoleon told Haussmann to do: aérer, unifier, et embellir. Give it air, bring it together, and embellish it.
Oh, and parks. Big ones. Oh, and two monumental train stations. And an Opera House. It cost a fortune and took 20 years, but in the end there was the Paris you know from pictures or trips, a unified work of art whose ideas spread across Europe, and then to America.
