I have nothing to do with this case, but it is an interesting read.The family of a man who from the upper deck at Turner Field filed suit Tuesday against the Atlanta Braves and Major League Baseball, claiming negligence relating to how high the guard railing should be. The lawsuit claims that the railing in front of Section 401 was only 30 inches high.
I have been in that area and while I may be a little bit apprehensive of heights, I do remember that the rails seemed lower than in other places.
