Falling Rock

Driving through the mountains of Tennessee and North Carolina on the way to Myrtle Beach, it was quite common to see signs warning of rock slides. We've all seen them. "Watch for falling rock", "Falling Rock Zone", "Rock Slide Area" etc... You don't really give these signs much thought until you see photos like the one below. If you really think about it, the rocks in those road cuts could give way at any time... and you don't want to be below them when they do.
