Epilogue: Safelite came out a few days after the rock hit the windshield and the crack doubled in size and they said it was too large for a repair. They also said that the line that they can repair something smaller than a dollar bill is not true. I had to take it in to their shop for repairs so that they could recalibrate the safety systems. Took two hours and I was on my way. I've added glass coverage to my auto insurance.
