Makes sense. And funny thing about the swabs. I know there is a huge shortage of them. Yet in the packet that they give you at the test site, there are two swabs in each packet. I'm sure it is for if you make a mistake and need to redo it. However, that is a huge waste of swabs, because they do not take those back and tell you to toss them when you get home. If my county is doing 40,000 tests per week, that is 40,000 swabs being wasted!
