In response to my last post, Meaningful Numbers, I got this link from a reader. It will take you to a map that shows, on a county-by-county basis (and we all know how I feel about counties) what your chances are of coming into contact to a corona virus carrier at large in your community.

In using this tool, you should note the slide bar at the lower left, allowing you to view risk scaled to the size of the gathering you are contemplating attending. You should also note that the data assumes there are ten times as many infected people than are reported in official figures. I wouldn't have doubted that figure a few months ago, before widespread testing became available. Even now, the public's indifference to getting tested, even here in San Antonio, where testing is free and easy, leads me to think that ten times the reported figure probably isn't off by much; and it's best to err on the side of caution in this case.
If you're thinking of going where there'll be a number of other people, a place where social distancing will be difficult, unlikely or impossible, that web site will help you make an informed decision as to the risk it entails. But you should also remember that, if you go, and you're exposed, there is still the After-Time to think about: a time when you will return to the company of your loved ones, when you may yourself be the infected one, when you will be the source of illness and death for everyone around you.
