CFish, you can do the Rock Jetty, just have some patience and a good anchor.
I took my 15 year old and a friend last week and we caught about 30 in 1.5 hours, kept enough for dinner. They had a great time and it was just as fun watching some tots in the next boat catch fish too. It is a different experience, but most everyone is nice.
We used white Gulp 3 inch mullet minnows on a carolina rig (one once slip sinker) fished on the bottom very slow. We caught most our fish quite a distance off the Jetty - don't feel you have to be right on it to catch fish - you can be in the "second Row"
