People come to vacation and think the Great Lakes are just like the oversized ponds most places call lakes. They are actually fresh water seas with all that implies. No sharks, yet. But they can be very dangerous.
I’ve taken some pretty good rolls on a sub at 100’ feet deep. No way I wanted on a tin can surfaced. The Great Lakes ain’t nothing to screw with.
A friend of my parents had a large yacht on Lake Superior when I was a kid and they would take us out for a few days.
One time got caught in a bit of quick sand as I was walking between two islands! It wasn’t very deep, but sure surprised me.
Those trips were always fun as it was so much different than my usual summer activities. Mostly at our shack of a cabin on a lake. Cruising around in a REALLY fancy yacht, exploring the islands on the south side of the lake and spending the evening on the boat in my own room!
Went across the lake and met up with his son on the son’s yacht in the middle of the lake, at night. This was back before GPS so I was pretty amazed at that. I guess using the charts got them close and then they used their radar. But still, as a young teen that was pretty cool.
