That when my wife went out to warm up our "beater car" to pick up my son from daycare, the back windshield cracked and flew everywhere. She called me at work all in a panic explaining that she turned the heater on to heat the window and she heard a pop and a crash. She looked back and this is what she saw.
The car is currently at the shop awaiting a new window. We are so lucky Rowan wasn't sitting in the back of the car when this happened. Ugh!
