First of all, the former Corbina-man is now living in the Lake Tahoe area. A 215 miles drive to the saltwater in NorCal. No sandcrabs here but plenty of crayfish in the Lake!
I came across a iron lure that I can't find on Google so I'm hoping that a Calfisher will know something about the Happy-A jig by Happy Lure Company, Redondo Beach, CA. Looks like an anchovy with a small tail and a prominent dorsal fin.
