When they were interviewing David Ragan and they asked him about the hole in the track he replied something like, "I don't know why they just don't put one of those orange cones in it and get the race started again."
He said exactly what I said to my wife a few minutes after they red-flagged the race.
They say a picture is worth a thousand words, or a thousand minutes in this case (at least it felt like it), so I'll let the picture write the rest of this post.
