I Live by Logan Martin & Need Crappie for kids.

I need somewhere to take my 5 kids. They hardly ever get to go fishing. I would LOVE see them really find a school of crappie, so each one could catch something. My set backs are, no boat, and it needs to be kinda close, and cheap, plus I can't get hot, or do much walking.(because of illness) When I was a kid someone use to take me fishing, and there were several different places in the area where we would set on rocks unders bridges and could catch Crappie all day long. But now I have no idea where to find any bridges my kids can sit under and catch fish. If anyone could tell me the location of his "Super Secret, Fish Filled, Honey Hole" location, it would be greatly appreciated.
