When Bill arrives in Deadwood for the first time, just after the Stagecoach door opens, the camera skips to the next angle behind the Stagecoach. Bill steps out as if the carriage has just stopped, however, the mud that the wheel has accumulated has dried on the tread part in clumps. If the Stagecoach had just stopped, the mud would still be wet on the tread of the wheel. If the road were dry, the treads would be clean as the rolling wheel would have broken the dried mud loose as it rolled against the dry ground.
