I was diving at Three Graces on 7/12/02 and 7/20/02. Both times visibility was 4-8ft with 8 at the bottom. Best way to get crabs and good clams: surface swim to the second rock and drop down to 37-42ft. No lingcod, just few rockfishes. Take flashlight. Dive at high tide, since shore entry is difficult at low tide. Have your hand truck with air tires with you: it's about 70 yards walk on crashed rocks along the railroad way.
