In a related story, a woman in her RV at Texas Motor Speedway was severely injured when a .50 cal round came through the ceiling and hit her in the arm. They figured the round had to have been fired from some 2 miles away. Never found out who shot it (DUH!).
Just as bad as shooting into something that will bounce back at you.
I've seen sometthing similar to this happen, but the reason he isnt dead is because it hit the ground before it hit him. Watch the ground carefuly just before it hits and you'll see what I'm talkin about.
