Vince,
It's pretty easy. Go N on hwy 65 to Louisburg, turn L (West) on hwy 64 go to the stop sign (road will t), turn right (still hwy 64), go through Pittsburg, as you are leaving town you will see Whites Marine on your left, just past it is Hwy 64B, turn L on 64B. Follow it until the hwy turns to a state park road, the marina is on your right but just keep coming and the road ends in the water. If you need any help just call 417-848-7719.
