I saw 12-15 otters yesterday while paddling off Lover's Point in Pacific Grove, CA. I say 12-15 for I kept my distance, as one should, and can't confirm all of the sightings. #13 or 16, for example, was a small log, when I drew much closer. At another point, one fellow surfaced suddenly, chirped strongly at me, and dove down so fast I only had that cry and a sense of a furry brown head, but harbor seals and sea lions don't chirp like that.
(A fading swell helped make the paddling a little fun too; I dislike lakey, flat conditions, but that swell also kept me from poking in among the shore rocks and surge channels too.)
