One last ride for Chicago boat pilots

It's the end of an era for one Chicago family who has been part of Chicago's rich history for more than a century. After four generations working on tugs and fire boats in the Chicago River and Lake Michigan, the Schmidt family's reign on the river is ending.

Even though none of Bill's kids decided to work on Chicago's tugs or fire boats, one of them chose service on the water. To his delight and surprise, daughter Heidi joined the United States Coast Guard in 2007 and graduated as a Lieutenant. Heidi and her husband Taylor continue to serve in the reserves.

Photojournalist Erik Arendt did much of the heavy lifting on this report.
