Next time your flight is cancelled, consider this inspiration to get creative.

When a cancelled flight strands you in an unfamiliar city for a day, you have two choices: moan and groan — or make the best of it.

San Diego resident Pat Flynn chose the latter.

Flynn is an expert at making something out of nothing. After losing his job in the crash of 2008, his YouTube page explains, he ventured into the world of online marketing, and became a huge success.

On Friday, he treated his 129k subscribers to a video that wasn’t about how to “earn passive income” or “write bestsellers.” Instead, his many fans got a miniature tour of Philadelphia.

Giving the keynote at the Podcast Movement conference was the reason Flynn and his 8-year-old son Keoni were in town. Flynn, now 35, had only visited once before, on a daylong detour during his eighth grade trip to Washington D.C. So when his plane was turned around on the runway and eventually cancelled, he and Keoni decided to explore.

Left without their luggage, the father and son woke on the morning of their unexpected overnight Philly stay with no agenda and a whole day to fill. So they hit upon a plan to visit as many local landmarks as possible — and do a dance in front of each one.

They dubbed it the #landmarkdancechallenge.

Over the course of six hours, assisted by 12 different Uber rides, they managed to visit 10 iconic Philly spots. And for folks who didn’t have any time to prepare in advance — they relied on Google, per Flynn — they made some solid choices.

The agenda included:

Liberty Bell

Independence Hall

Betsy Ross House

Reading Terminal Market

Art Museum steps

Franklin Institute

Pat’s and Geno’s

Spruce Street Harbor Park

LOVE Park

Favorite of all the spots was the Franklin Institute. “They had a video game exhibition while we were there, which was an awesome bonus,” Flynn said. “But we’re also both into STEM education and hands-on experiments.”

As for the cheesesteak question — Pat’s or Geno’s — Flynn’s son could be a Philly local in disguise.

“[Keoni] said he preferred Jim’s over both,” Flynn admitted. He himself went with Pat’s, partly because they share a name, and partly because he was into the more frizzled meat, as opposed to Geno’s long strips. “Both excellent though,” he clarified, “and unlike anything we could ever get in San Diego.”

Flynn doesn’t travel all that often, he said, but this was a special trip with his son. Even though it had a twist at the end, the duo enjoyed themselves.

Keoni termed the landmark tour “our Philadelphia adventure” — and it was enough fun that Papa Flynn ends the video by saying they’ll definitely plan a return visit soon.
