Bacteria, squishy mud you sink into with glass from teenagers drinking hidden all over and you cant see the bottom even in 2 to 3 feet because they are almost all murky, bacteria and contamination because no tides or flows, leaches, snapping turtles. Havent done it since i was a kid. Thats my own phobias though. To be fair i dont do the ocean either so that leaves a pool when i can find one. The ymca is boycotted....

I started being vague lately because some people (IRL) think it's really funny to prank me. They don't understand that I know it's irrational but I can't help it. It's the S word. People that don't understand say, "Oh that's just a garden one, it's not poisonous." Neither is a purse, bag, belt, or shoe but if you put any of those in my hands I'd probably have a non-jab-related coronary event. At a cub scout event years ago I was teaching my part of the meeting and learned that the wrangler we scheduled for the boys had stowed her bins of friends behind me in a corner the whole time. I don't remember how I got out of that room and down the stairs into the parking lot but I damn near needed a 5150 hold after that.

Not OP, but for me, a lot of older developments on lakes around where I live have sewage systems that go right into the lakes. 🤮
