Just a reminder, if you're in the US and uninsured you can probably still get free PCR covid tests at chain pharmacies. Be sure to "prefer not to answer" about medical conditions, and you can probably assume you've been near people that have gotten covid if you were at a convention in the past week.
Even if you don't have symptoms, you can probably get a same day appointment for the drive through. If you've got the time and the resources (read: a car), go get tested.
