I've told the story of the rolling stones. I feel like it's gotten lost.

The biggest stones you will push to roll down a steep mountain will amaze you. They will break through small trees and stop at little.

I discovered this in a deadly situation with my friend and housemate Tom. What we didn't realize until the end was that there was a road at the bottom of the mountain. We were watching stones roll through trees down the Tennessee mountain into a river. That was all party time fun until we realized to out horror that there was a road hidden between us and the river. We found dents we had marked in the road but no derailed cars.
