Watch out getting on 575 N at Bells ferry

I would like to report an incident that happened to my daughter today as she was getting on 575 from Bells ferry heading North. Right past the flashing light. When a rock hit her car and smashed her back rear window. She called the police and he said he agreed that someone must have thrown the rock. She and I are so thankful that it did not hit the window where her 2yr old was sitting. This could have been a lot worse. I just pray that it does not happen to anyone else. Be careful.
