Flying In/Out of GEG

Hey y'all. Just a heads up that if you choose to fly somewhere from the Spokane airport after driving across the border. So as the rules stand (right now), say you drive to Spokane and fly anywhere out of the US like Mexico, when you fly back and then drive back over the Canadian border to go home, your PCR test (assuming you went to Mexico for more than 72 hours) MUST be done in the USA. If you get the PCR test in the country you were in, fly into the US, then proceed to the land border, ONLY  a PCR test done in the USA is valid. It's a technicality that I lived and learned yesterday so you don't have to! 

good to know. thanks
