While reading on the internet recently, I was reminded of a passenger...
The pickup address was at the Mercedes Benz dealership on Scottsdale Rd just north of Frank Lloyd Wright. The passenger was a single gentleman who I estimated to be in his mid-70's. I asked if he'd dropped his car off for service. He said that he'd dropped a car off at the auction, across the street, and was going back to his condo for the other car that he was selling.
One of my standard questions was to ask people if they'd lived in Phoenix all their life. If not, I'd ask how they found their way to the desert. Then I'd just go with my intuition to figure out if this person had something to share that I'd be interested in.
Maybe because he was old, or because I was just a random taxi driver, he told me of some things that younger retirees with security clearances would have never even hinted at.
