All it takes is a little bit of seaweed dangling on the line. They see movement and snick! she's a gone. Think of all the lures you find when the blues are hot and heavy. Cut just above the leader, aren't they? Little bit of weed at the swivel. Chomp = gone!
He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself.
Thomas Paine
There's a couple of south facing beaches on the Cape I love going to when it's low tide early in the morning , you wade out and find all kinds of lures , a lot of new ones, just like BBJ said , bitten off at the swivel.
