Will you have a boat? Are y'all looking to catch specific fish or just have a good time? If y'all are on foot, take them to rollover pass. Regular bass rod/reels work fine. Rig the rods w/ Carolina rig setup. Use live/dead shrimp, mullet, shad or live croakers. Y'all will catch fish. Bring enough back up tackle cause you will lose some. Bring a net with a long handle to get the fish over the rusted wall. You will catch specks, reds, sand trout, croakers, hard heads w/ the occasional flounder. I'd bring you some string and chicken too. Great crabbing at Rollover. Hope this helps and hope your nephews have fun. Also, make sure you give your rod/reels a thorough rinsing after you get done each day. Saltwater is brutal on the reels.
