The wharf typically bustles this time of year as dozens of crab fisherman prepare to haul millions of pounds of Dungeness crab that are a tradition at Thanksgiving and other holiday meals. But crab pots are sitting empty on docks, boats are idled and fishermen are anxiously waiting for authorities to open the lucrative Dungeness crab season. (AP Photo/Eric Risberg, File)
