That’s a great find on your camera and you knew where to place it. I used to live in an area with a lot of otters (Marin County, CA). I’d see them in the lagoons, bays, and fresh water lakes frequently. My dog even played with one that surfaced in a lake one time. I did a post on my blog with some great video footage link to youtube that I took while standing at Abbott’s lagoon watching it all happen. Maybe you’d enjoy it.
