Check out ozarkanglers.com. Go to the forums, and then Table Rock. Some great folks posting, with several guides. Went down last summer, and just followed reports from the sire, and did O.K. It is very different than fishing most lakes though. There are several guides from the site who give great, free posting info. If I were going to be making it a fishing trip I would for sure hire one, even for a half day. Lots of them will spend the time just discussing options and areas to fish while showing them to you if you prefer.
It was a brave man who first ate an oyster!
