+    Technically, `pathMatch = 'full'` results in a route hit when the *remaining*, unmatched segments of the URL match `''`. 
+    In our example, the redirect is at the top level of the route configuration tree so the *remaining* URL and the *entire* URL

     The other possible `pathMatch` value is `'prefix'` which tells the router

+    to match the redirect route when the *remaining* URL ***begins*** with the redirect route's _prefix_ path.
     
-    That's not what we want in our use case. The `''` prefix path matches _every_ URL.
-    We should redirect to the `CrisisCenterComponent` _only_ when the _entire_ url is  `''`
