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 Sabatier, host of the podcast rendered formerly 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 decidedly 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.
