On Christmas eve-eve I was driving do my G-pa's house in northern LA. On the freeway traffic started to get congested and we noticed on the other side that there had been an accident. If you look at the top right of the picture you will notice a trailer with wheels on top of it. Well, that wasn't the top of the trailer it was the bottom. The trailer and the SUV were upside down and backwards. I don't know how they did it, but is sure was a good trick.
