Wish I could help more but I know very little about Cave Run crappie fishing. It's about a 1.5 hour from me too. What few times I've been there we launched out of Scott's creek. It's been several years since then & we were bass fishing anyhow. I have a few friends that crappie fish around the marina successfully. Fall fishing in our area can be the most consistent time of the year. You guys might get into a big Musky there. We used to scuba dive there back in the day.
