One of the puzzles about clamming is how slowly it goes at the start. It happens almost every time: No matter when or where I go, after I step into the water and drop my rake I find nothing for several long minutes. Then, there is a familiar clunk as the tines of the rake strike the first clam, and then another, and it is on. This may reflect some kind of truth about nature and humankind, but I’m not sure what that may be.
