Yeah, we don't seem to have all that many members that fish Cave Run, let alone specifically for Bluegills. Personally, I've only fished it for Crappie, Bass, & Muskie over the last 5 decades ... and not all that often in the last decade.
I think the only lake I've actually fished "specifically" for Bluegill was Herrington Lake .... Summer spawns with crickets or early Fall (Aug) with Horseweed Worms, back in my youth (teens & twenties).
