Very well written; I cringed when I imagined being on that slanted ledge!
Compared to your story and Omni's, mine is much less dramatic, but here goes.
One day when I was 11 or 12, I walked down to the country store. I lived in a rural area, and the second nearest store was 5 miles away, but farms were plentiful. As I was crossing the road, A tractor was trying to make a left hand turn, but since they move so slowly I didn't feel in danger at all.
The look on the farmers face was that of terror; he was looking behind me, and so I looked. As I turned, I heard the shrill scream of the brakes as a car was speeding right toward us.
I jumped into the ditch on the opposite side and felt the collision just a few feet to my right. The farmer stayed in the tractor throughout the whole ordeal and the lady in the car was seriously injured.
As far as I know, that's the closest I came to death.
