Since the 1950s, the city of Detroit has lost half its population, which now stands at about 900,000. Entire inner-city neighborhoods have been abandoned, often burned out, and eventually bulldozed; Google Earth shows the downtown ringed by hundreds of blocks of grass and trees.

The blight has spread now to neighborhoods far from the city center. First one family, then another, leaves town in hope of finding work. They cannot sell their homes, but they leave anyway. Soon, their neighbors are leaving also, because semi-abandoned neighborhoods are dangerous and unpleasant places to live. Here is a picture from last summer of a Detroit neighborhood with just a few homes still occupied. By next summer, there will be fewer still.

The weather was raw and wet a couple of weekends ago in Bethesda,Maryland,  but the artists all showed up anyway with their tents for the annual art fair. The street was closed to cars, and I got to wondering about all the traffic arrows painted on the roadway: Did it cost extra for a booth with an arrow that directed traffic right to you, as opposed to one where the arrow on the road seemed to be steering people away from you?

I was also curious why the same lane on the street seemed to be painted with arrows pointing every which way.

In the end, I'm sure the arrows made no difference; the weather kept crowds thin all weekend long. The band kept playing on the makeshift stage at the corner, and the vendors kept hawking crab cakes and curry, but I hope the artists enjoy better days soon.
