Throwing OVER a Dead Ball Area

[BJ Moose]

We have a field like that. Past dugout then fence goes 90 degrees and foul about 40 more feet. Ground rule is that a ball cannot be thrown over this "bermuda triangle". I asked WHY, and at least got a reason.

In a game, a player had retrieved a ball deep in that corner and attempted a throw to home, a path over the triangle.. but in that triangle is a pole, ball hit pole, carommed into stands, hit old lady.

Ok, at least is is a reason.
