One thing I learned from my boat owning days is that any body of water will try very, very hard to kill you. Oftentime in very unexpected ways.
I still remember falling into a pool at 5 years old, unable to swim. Nobody saw me. I was lucky I was next to the ladder, saw it, and just climbed up and out like nothing happened. I was more worried about getting in trouble with parents than anything else.
After being out on an 18 ft skiboat in Little Traverse Bay when a storm started to hit (Lake Michigan), I have a real healthy respect for water.
