If it rains that much just about all the lakes in southern Il are going to look like chocolate milk including Kinkaid. And if the wind blows there are plenty of boat ramps around Rend to find good coves to fish out of the wind. But I do know what you are saying, Rend is a BAD place to be if the wind is rolling. Don't give up on Rend but I don't blame you for wanting to try Kinkaid also it is an awesome crappie lake but hard to figure out if you have never been to it. Good luck with your southern Il adventure which ever lake you go to. Hope you catch some gooduns.
