waist deep maybe not good for diving? feet out head on the bottom?
reminds me of out ponds in oklahoma when i was a kid. the water was three feet deep with soft mucky mud on the bottom many feet think. we'd dive in headfirst from way up high, and be stuck headfirst into that soft mud. feet sticking out of the water. we'd pull ourselves out with a nice underwater sucking sound....
the cows thought we were crazy
