Anyone who has done trackside motorsport photograghy will have a story of 'that' close call. Mine was about 10 years ago when I hit the deck behind the armco to look up afterwards and see the underside of an X19 balancing above me.
Not that you should know (I'm not the repost police) but that was posted here the other day and was moved to the Drag Racing forum, I think there's a topic running over there about it
