When you find out where you are going, get a map of the area. Big lake, and you can get lost. You will be there while the lake is at winter pool, so take that into account when reading your map. Some spots are pretty shallow at winter pool and that helps send the local outboard mechanics' kids to college.

Be aware of conditions. Big lake, big waves. It can make a 20 foot boat bounce around like a cork. Don't mean to scare you, just be aware.

There are several online fishing reports that will be very helpful when the time gets close. Try http://www.kentuckylake.com/ to start, and check in here.
