Rev. Prostata Cantata, an actual scientist, regards the "swimming hole." It has a somewhat squishy mud bottom but not much in the way of gross algae. It does hold many life forms such as frogs and salamandars. I am an amateur scientist with an interest in microscopic creatures and I will probably bring my microscope so as to observe otherwise invisible animalcules. (Due to the filtering I don't expect to find as many as I might have in the kinds of swimming holes I used as a boy in the previous century.) I am not afraid of the pond but I can see how younger "TV People" might be. But it is regularly inspected and swimming in it is probably much safer than, say, driving a car. Also, we can do the post-Bobtism "whirlpool" that was prohibited at the Brushwood pool.
