Was up at the St. Lawrence Seaway recently and Connie took me to the Eisenhower Lock (she had run a restaurant in Massena, NY) and said this would be very interesting for me and it was. Connie and I had done our share of locking on the Mischief but that was very small potatoes by comparison. They run those ships through like a toll booth. Just one bin of the bulk container loaded with concentrates . . .
