Was on a walk at a Jugg Bay park in MD with my then girlfriend. Happened to take my camera and a long lens along. There's a long wooden bridge across the river and we heard a noise. Saw these guys swim under it and pose on a log. In the several years we've been visiting this park, neither my parents nor I had ever seen or even heard of river otters in the park.
