I doubt it, but you can check the harbor cams during the day. http://www.duluthharborcam.com/p/blog-page_13.html
As we drove into Duluth Friday afternoon there were 4 ships outside the lift bridge waiting. It was stuck down from ice after the big storm and I think it just got running again Thursday.
Most places are saying 10 to 12 inches with part of that white ice. Sounds like the big crack has about 6 inches of ice now. The big crack is hidden under the snow now, just waiting for someone to be careless.
Check Harbor Freight or Costco for a variety of LED battery lights...
The little blue ones harbor freight gives for free with coupon work well. 3.99 without coupon. Run on AA batteries.
