It is winter time most definitely here in Michigan. You can tell by the normal way of things, the snow, the ice, the car crashes. You can also tell, because it is the time of year when the Soo Locks begin to shut down. MacArthur Lock is now closed until early April. However, if you have cargo coming in via the Great Lakes, don't worry overmuch. The Poe Locks will remain open for just about another month yet.
