Im staying in cherry grove sc ( just north of n myrtle beach ) ive got a shore fishing rod with a spinning reel loaded with 20# momo. Any tips on shore fishing? Do i cast out in the breakers or past them? Do i let the bait im using ( shrimp ) sit there or do i need to reel in the whole time? Help asap please. All ive been able to catch so far have been 6" spots? Some old guy told me thats what they were.
