Joe F, thanks for the link to the ferry terminal videos. Many a time I came across the North (Hudson) River on those ferries. I remember that streetcars, with their open sides in the summer. On a warm day, with a southerly breeze, there was an overpowering stench of hot blood from the New York Butchers Dressed Meat Company slaughterhouse a few blocks down. Those ferries had reciprocating steam engines, great to watch down the gangway hatches from the car deck.
