I used to live in a town with heavy and frequent railroad traffic; freight and passenger. The annual fatality count was amazingly high, even with all of the safety equipment and flashing lights the government could think up. Same idea; some things you just don't mess with, RIP.
A guy was peeing off the back of a boat while out fishing. The others looked back and he was gone. They could see him in the water, but the ten foot waves prevented them from reaching him before he drowned. Superior is a wicked and cold lake. This story was near Munising, Michigan many years ago.
