Danger due to Open Hole Sep 1, 2004

Brad pointed this out to me. Now, I understand the place is a little dangerous. I've noticed that there are GIANT-SIZED GAPING HOLES THAT YOU COULD DRIVE A TRUCK THROUGH. Is the little sign informing me, 'Danger Due To Open Hole' really necessary? If ever there was a case of pointing-out-the-obvious, this takes the cake. And the pie.
