They didn't give them away. It was the early 1960s. They would collect massive amounts of clams too. I believe it used to be motorized. I remember that. There are some statistics here, but I don't really understand them. A bucket of clams used to go for less than $1, and it cost $4 in 1970. The canning factory closed down at one point.
I remember going to harvest clams and having a swim. When the tide was really out, we'd walk up to the end of the sandbank, sit down in the water, do some digging and wrap clams in our sweaters. The sunburn would turn our backs purple. We'd build a bonfire on the beach in the evening and have a friendly clam bake. Those are the things I remember. I'd also go fishing with my father, who was pretty fast, and I had to keep up with him and pick up the clams.
