I flew into the Portland Airport recently, and when I got off the plane, I took a picture of my feet, in keeping with the local custom.

A foot selfie.

That's producer Julie Sabatye, host of the podcast rendered, formally known as Destination DIY.

She lives in Portland.

And I almost always take a foot selfie when I'm at PDX, the Portland Airport.

I think I do it most often when I come home. Like, here I am. I'm back in Portland.

The feet are actually not the most important thing about a Portland Airport foot selfie.

It's actually what's under your feet. The famous PDX airport carpet.

It's allowed to suddenly 80s teal color with a repeating geometric pattern.

Like any carpet you might see in an airport or a hotel lobby or an office building, it's probably not what you'd choose for your living room.

The design I'm told is based on the way the runways and lights look from the air traffic control tower.

And also on the radar screen that the air traffic controller sees with that sweeping line going around and around.

And the dots are the little blips representing airplanes.

It's hard to say if it's the pattern people are responding to or the bright teal background color.

But one thing is for sure. The carpet is very, very beloved.

There are even signs in the airport now saying, tweet your feet with the hashtag, PDX carpet.

And it goes deeper than that. Meet Emma. She actually has a PDX carpet inspired tattoo. It hurt a lot.

Emma Milken is a 21 year old Portland native, which means a lot of the carpet in the airport is actually older than she is.

She got a tattoo of the carpet pattern on her back. This side. So yes, my left. Emma traveled a lot as a kid.
