Portlanders have a tradition when visiting their Oregon airport: taking pictures of their feet. It’s not to show off their shoes but rather what’s under them. They are documenting the famous PDX carpet: a loud, decidedly ’80s geometric pattern over a vast sea of teal. The carpet, it is said, is based on the way the runways and lights look from the air traffic control tower. It is very beloved, with signs at the airport saying “Tweet your feet”, a #pdxcarpet hashtag, and tattoos. But now, the carpet is being removed, and locals and passengers are up in arms.
