What is the purpose of the tug boat that met the Houston in the harbor?
What I have heard is some of the salt water captions don't always know there way around Duluth harbor,,,also most of the salties don't have bow thrusters,,so the tugs help them get around..
Salties are required to have an escort.
On the subject of salties, why don't they give a captain salute when they arrive or depart? I've watched many come in and none blow their horns.
