All the silvers I've seen in the salt this year are completely lock-jawed. I'm glad I'm not the only one having difficulty. I've tried lighter leaders, smaller lures, even the flyrod but with virtually no luck. I've had days like this in the past but not weeks. The fish I've seen are feeding too but I just can't tell what they are locked in on. It seems similar to trout that are completely dialed in on one specific insect and won't touch anything else.
