Windshield chipped

Finally remembered to take pictures of the WINDSCREEN CHIP I picked up on the recent MAMA drive last weekend … my first chip, perhaps because I normally try to stay well back from the car in front, but on the rally we were all trying to keep close together!
There were two loud bangs during the day, with a stone flying up and hitting the windscreen – both left chips, and one in particular is a noticeable 1/4″ notch. I might find out about having it filled. At least the screen did not crack, but it is a bit surprising that it even chipped as we were not driving at highway speeds …
