“While we’re in the USA, maybe we could go see New York?”

“Oh, no way. Forget about it. So depressing.”

“No, really, I think it would be good. For the kids. See how they used to live.”

“What - stacked like rats in a hive?”

“Come on. It was a center of the planet’s commerce and creativity.”

“And now it’s a thousand square miles of rust and rubble. I don’t see spending a day cruising over that wreckage on a guided dirigible tour as part of my holiday. Picnic in a weed-choked Central Park. Photo op with the pediment of the Statue of Liberty. No thank you.”

“Well, I had something else in mind.”

“… OK, what are you up to? I know that look.”

“What look?”

“The one you’re wearing. What is it? Spit it out.”

“I know someone who does ground tours. On Manhattan.”

“Manhattan? On a walker?”

“No. On foot.”

“Really? … Is it safe?”

“Oh yeah. This guy’s very good. Fully certified. Provides all the safety and security equipment, too. Drone cover and everything.”

“Hmm.”

“Yeah. And there’s more. He says he’s seen humans living down there. Says he knows where they are.”

“Seriously?”

“Yup. He says we’d be guaranteed a sighting.”

“Whoa. That’s … Illegal. Is this guy legit?”

“Look, it would be a great opportunity for the kids. They’ve only seen humans on screens.”

“Why do I have a bad feeling I’m going to let you talk me into this … ?”
