It can happen at any time - and it did to us once. There we were, driving along minding our own business, when a big truck drove by. Nothing unusual in that, except that it hit a big rock as it passed, and that big rock came flying towards our windscreen.

To say that we were shaken was an understatement. We had been going to visit relatives on our way to a holiday abroad. We had set off early and were making good time. But now, we couldn't see. There was glass all over the car (luckily not too much on the baby's car seat) and all over the front. What were we going to do?

What we eventually did was go back home and swap cars and start again. As it turned out our auto glass replacement service couldn't get to us in time and as we were flying out the next day, there was nothing else we could do. So we couldn't see our relatives and arrived late at our hotel. Instead of feeling refreshed, we felt jaded and tired. Just as well we were going on holiday. So it's definitely worth getting the contact details for a mobile auto glass service, such as the Nu Pro Auto Glass in Fairfax (tel: 301 574 8000).
