I may have posted this before - at my age you do repeat yourself.A very nice site here about Lake Freighters including AIS positions. www.boatnerd.com I saw the 730 ft. Canadian Minor pass by the house today - first freighter of the season. We don't get the 1000 footers here becasue the Welland's locks only take up to 730. The Welland opened on the 20th so the lake freighters are shaking out the cobwebs and getting back to work. Spring is coming!
