I dont know what pin rig is, but if it uses some kinda method of floating, like a cork/ballon/etc then they wont let ya use it
However, what I do is I use a king rig set up ( just the wire and hook with treble hook set up ) tied straight to my line with a live finger mullet on it and I just let him swim around freely, letting him dive away from the birds lol
Can catch big Spanish this way, but not sure about king mack.
I wish they would fix the end of the pier and allow king fishing again, but from what I under stand, the man who owns the pier wants the thing to just rot and fall into the ocean without ever rebuilding it
Very very very un-fortunate for NC to see its piers just fade away like this. All we will be left with is the state government controlled piers, and I do not have my hopes up AT ALL that I will enjoy those piers, but we will see.
