I spend quite a few days down there. I usually stop fishing KY and Barkley First of June and start back up around Middle of September. I suspect you can find places where the pleasure boaters and jet skis will leave you alone, but those spots are few and far between.
Night fishing would definitely be an option.
Also, I will let you know in a few weeks......I'm going down with my wife for a weekend in a couple of weeks, and I suspect I will have a bunch of folks to deal with.
Later,
Geo
