Might flow from necessity. Or from Frank Zappa. (My favorite Mothers ditty is at https://youtu.be/wMSQ1vCxZJU. My daughter and I used to sing it together when she was little.) But the phrase is an old English proverb and it is often true. I got nothing to shoot. My brain is empty. I shot this on my drive home from work. Yes, I was driving but it wasn't so bad. Before I got on the highway I set the exposure, turned on autofocus and put the shutter on burst mood. Then, when I was on a straightaway, I propped the lens on top of the steering wheel and, without looking, fired away. And so, the blandness of the American suburban commute.
The sign with the bright numbers is promoting the two main lotteries in my state. It's a con game on so many levels. The two numbers represent the current jackpots in millions of dollars, but that's not what you get if you win. It's the sum of the payments of a 20 year annuity. If you want the money in a lump sum, as all winners do, you get a far smaller amount. Someone said that lotteries are tax on the stupid.
