There is no sadder place than a race track in the rain.
Unless it's a road course, no cars go out on the track when it's wet, and in NASCAR, only the NASCAR XFINITY Series has done it. Those were on a road course as well, in Montreal and Wisconsin.
When Mother Nature is on a rampage and pop-up showers bedevil the paying public, what's a racer to do?
If you're NASCAR, you call for the Titan.
