Horse crap is the last thing I would worry about. As recent as the 001212 swell, if you had walked the beach that morning, what you ...should have noticed were all those GREEN Turds up on the beach at the high tide. It happens more then people know inOCMD,I think it comes from the local sewage plant.
What I have come to ASSume is that depending in swell/swelldirection/tides, etc. The local sewage plant Either backsup, overflows, or something.
small fairly uniform green turds, like what you would see at a treatment plant.
