Wow, that name brings back memories. I used to go to Dale Hollow when I was a kid or should I say about 20 years ago (my wife still thinks I'm a kid).
We lived in Ohio at the time and would rent a Houseboat on this lake every summer. It was a blast! Unfortunately, I don't remember that much about the lake other than at the time it was really worth the drive! The water was pretty clear with a rocky bottom (little flat rocks-good for skipping). I believe the lake is partly in Kentucky and partly in Tennessee. I think the lake is huge with lots of coves and forks in the lake - I can remember my dad getting lost in our ski boat trying to make it back to the Houseboat (cussing alot of course)!
Don't know that this helps much, alot can change in 20 years - I know the lake here in Conroe, TX has with all the golf courses and houses frown
