Wednesday afternoon found a rare sight on the North River: towboat Buchanan12 returning to her Erie Basin base running light without her usual raft of crushed stone hoppers from the Clinton Point quarry near Poughkeepsie. The next morning, Norfolk Tug’s George Holland, who sometimes substitutes for B12, was running with the Buchanan boat’s usual charges, returning empty BMLP hoppers to the quarry. By Friday, both were back to their more usual routines, with Buchanan12 moving hoppers between Clinton Point and the Greenville Flats and George heading north with her single barge to collect stone for delivery elsewhere in the region.
