I heard back from Brian Tanner. He has been in a remote area of Michigan for a couple of weeks taking care of his very sick mother with very spotty cell service and hasn't been on email as a result

Hi Mark and All, I called Brian and texted him so will let you know when I hear from him. The COVID nastiness will likely surge again as several states prematurely remove the mask and social
