The "idlers" in the foreground are holding down part of the Atlantic Wharf on the north side of the Buffalo River between the Evans Slip and the Commercial Slip. The elevator in the center of the photo is the place to which the ships (Buffalo & Erie County Naval & Military park Park) have been relocated.
Note the two harbor ferry boats in action. For more information on the harbor ferry boats, see John Montague's story in the Spring 2003 issue of the Western New York Heritage magazine.
