When we lived in California, we had a 30+ year old tree by the street outside of our front yard fence. One day I go out, walk under it and pick up the newspaper that was on the road. I stand up and see this angry driver just stopped in front of me on the road. I can't figure out why he is stopped there or why he is giving me that look. I turn 180 degrees and there it is, the 30 year old tree had falling 90 degree to my path and completely blocking the road! We are talking about a tree with 4+ foot diameter trunk, weighing easily more than 1000 to 2000 pounds. Yet it fell so quietly that within inches of it, I didn't hear it fall. Needless to say, if it had happened just 10 seconds earlier, this forum would not exist.
