Went to Half Moon Bay on Sunday thanks to utbt. She told us about the negative tide. We parked at Pillar Post and walked about a mile and half to the reefs. It was worth it. Lot of people with children. The young ones were having fun picking the starfishes, mussels, hermit crabs, etc. People were allowed to harvest some mussels upto 3-5 pounds by the ranger. We saw some guy catch this 2 foot long eel. Super cool! Though bad for the eel. The weather was perfect. Apparently this event occurs a couple of times a year. I was completely awed by the Sea Anemones and starfish.
Here are some pictures.
