The mountains where I live are full of turning, twisting, narrow, curvy roads. I was driving down one of those roads last Spring. Days of on and off rain had made the ground muddy and hillsides mushy. As I rounded a curve I saw that the weakened soil had released a tree on the hill by the road. It was now laying on the asphalt blocking my lane. I hit the brakes and slowly drove around it. Then I stopped. I knew it was only a matter of time before someone driving faster than I was would crash into that tree.
