Big deep holes!!! It's so terrible to hear that such a lot of big-deep holes come out suddenly in so many places. How mysterious it is! I can't help thinking about if the scary prophecy about 2012 is ture or not. The holes had killed some people, I think the depth of the holes can just be made by the natural power and no matter about the human-beings. I hope all of these misfortunes are just accidents and no longer continue.
