Ah yeah, I don't think the Walgreens test takes that long, personally I'd rather know sooner than later to start that PCR 10 days clock. I mean you either test in Florida and know before you fly or wait and get tested in Seattle. You could order the Switch tests and do that yourself, either the Antigen or the RT-Lamp (which costs more). Or do the free one in Florida. I guess I just think I'd rather get tested in Florida than have to scramble and find a place to test before driving across? Then you know in Florida so you can decide, do you fly back to SeaTac and drive across, knowing you are positive on that flight but that you don't have to show that to fly in the US, or stay in Florida for 10 days?
