The waters of the Monocacy slow to near stillness mid-summer, when the moisture in the air feels equal to that in the river. At the end of a narrow dirt path, hemmed in by the stinging nettle, poison hemlock and japanese hops that the boys call “itchy plants,” you can find a deep, wide expanse of water that is more pond than stream. My old labrador likes to stop here for a drink (which I don’t advise unless, like her, you have a stomach made of steel). Yesterday, we both looked across to see a plastic bag floating on the surface of the lethargic water. It was impossible to reach from our side of the riverbank, but I did pick up a few fishing supplies. Float on.
