Matt, what's up. I had my BP on a house boat at the Ozarks last summer. Of course that is my home lake so I am very familiar with it. We had an absolute blast. I know you've heard stories about party cove from some of the other Memphis boys that come up every year. Houseboats book up quick for holiday weekends, so you probably need to get on it for Labor Day, but if you line it up I gaurantee you won't be disappointed.
