The Marine traffic site has been interesting in the past two days. https://www.marinetraffic.com While I saw the traffic jam build from the ship stuck Suez Canal I also saw many more dots start to show in Lake Superior including the James R. Barker on the way to Duluth. The ships back in Lake Superior are another true sign of spring. The James R Barker has the best horn on the lakes. It's cool to be riding mountain bike on the ridge above Duluth and know what ship is going in or out of the harbor. Look east on the map and you see the "salties" starting to head west. Very often they bring wind turbine parts into the great lakes and go out with grain.
