 Three years ago on the Tennessee River near Florence, Alabama, we had a failure of the Wilson Lock and Dam guide wall, which has really put us in a bad spot in North Alabama. It's been followed up by a failure on the Tom Digby at the Demopolis Lock and Dam. It took four months to repair, and now we have a near failure on the whole Lock and Dam on the Black Warrior River. So we're seeing these problems get old.
