AZ's solution to abandoned mines.

[BB-61]

FILL THEM UP WITH OLD TIRES!!

Hope Utah doesn't take a page from AZ.
Here's a link to the local paper here in Yuma on articles about this proposal.

There are also some articles included here about some guy that was leaning over the side of a mine and it collasped and he fell in.
He was ticketed but I think they should have charged him the cost of the rescue.
