I have an unfair advantage (a lighted dock). During the warm months of the year, there's almost always crappie coming there to feed at night. The mayflies also come to the light when they hatch and they accidentally fall into the water as they "swarm" around the light. The crappie are waiting just below the surface and when they see a mayfly on the water they pounce. While this is going on and the buffet is in full force, the crappies will bite jigs that are reeled by them while they await a mayfly or minnow that is coming to the light as well. It's the easiest time of year to put kids or inexperienced folks on some catching as a simple cast/retrieve will bring results.
My advice to you would be to find a lighted dock or two and set up away from the light so you can cast/retrieve through the light. I've found that dark body jigs (black/blue/green/purple) with chartreuse tails are the best at night for this technique.
Make sure you pay attention to what Jody tells you. He is an encyclopedia of "clarks hill" info, an excellent guide, and a great guy.
