Why this man poses in a CBC T-shirt as he globe-trots from Argentinian waterfalls to the Acropolis and beyond

Christian Muller, a dad from Calgary, takes his favourite T-shirt everywhere.

He's on an around-the-world trip with his wife and two daughters anda retro CBC tee.

Everywhere of note the family goes, so does Mueller, sporting the same outfit. He snaps a pic and posts it on his Instagramaccount, @Our4Afar, with the hashtag, #myCBCtshirt.

He says he's trying to find the "secret society" of other Canadian public broadcasting geeks who know the 1974 red, yellow and orange, exploding pizza-style gem.

"You're far away and sometimes you get homesick, but every now and then, somebody recognizes that," Muller said by Skype from Buenos Aires. "You have that conversation about home and it just keeps you connected to your roots, to what's important."

For the record, he prefers the 46-year-old logo as he himself was born "a little bit ago."

His family's got on board, gamely taking his picture by camels, waterfalls and well-known landscapes. They even gave him a new T-shirt at Christmas to freshen up his wardrobe.

'It's a CBC thing'

His blue tee, and often deadpan expression, will be in a lot of their photos but it'll help them remember all the people they've metthanks to his quirky habit.

They've been to 25 countries on five continents so far.

"It's always nice to be recognized by other Canadians so far from home. It's a CBC thing," he wrote in a photo from Iguazu Falls in Argentina.

Daughter AmelieMuller, 11, says she's had fun meeting other Canadians, like a tour guide of an Argentiniancemetery. The friendly staffer sported an Edmonton Oilers hat while relaying the stories of the graves.

"They ask us like where we are from and if he works for the CBC," she said.

"Of course, I have to say no," her dad said.

When on the Great Wall of China, a woman came running up to him. Turns out, her mother workedfor CBC Manitoba, Mueller said, and wanted a photo to send home.

Another tourist yelled at him, "Hey Radio-Canada!" at the Acropolis in Athens. That traveller once set his sights on working at CBC but went on to work at an arts museum.

"I've been listening and CBC for as long as I can remember," Muller said. "In the house, in the kitchen, doing breakfast, making dinners, in the car going to various activities when you're young.

"As I got older, it became important for me to stay connected to my community and to the world events around meI naturally gravitated towards the CBC, as well."

He still tunes into the Calgary Eyeopenerfrom abroad by listening online.

The family hasbeen on the road since 2017. Muller quit his business management job in Calgary when his wife, Jennifer, had the chance to work in digital marketingout of Hong Kong for a year.

Now she's on a sabbatical for a year. Whilehome-schooling the kids, they've explored southeast Asia, the Balkans, western Europe, Morocco and South America so far.

Muller said he wanted his kids to appreciate their part in the "global community."

"Just keep an open mind and an open heart," he said. "It'shard to hate others when you walked a mile in their shoes."

Right now, they're spending a few weeks in Argentina, where the temperature has hovered around 40 C.

They plan to return Calgary in July after a few more stops, including to Peru, where they'll explore Machu Picchu and do some jungle trekking.
