The freighters were sounding their horns because there were fishermen in the shipping lane.on the Canadian side. Detroit was at 99% of the eclipse, Luna Pier at 100%, so it was a little "darker ". It wasn't the darkness as much as the weird type of light at the pinnacle of the eclipse, for me. My third eclipse, and the best I've seen. Check out the Northern Lights [not the bar] sometimes in the UP if you really want to see a freaky light show.
