As a boy and father fish in the Clark Fork, eastbound Burlington Northern Santa Fe MPASLAU rumbles over the bridge at Bonner, Montana, on August 31, 2003. Santa Fe GE C44-9W No. 688 leads a former BN SD60M, followed by a Montana Rail Link F45 and two MRL SD45s, the last still in Southern Pacific paint. For the moment, the boy seems more interested in the train than what lurks beneath the water.
