I plan on trying Mark Twain this weekend too, probably on Sunday. I'd love nothing more than to get my kids into some keeper crappie. They are finally old enough to take the fish off the hook themselves, so I might even get the chance to fish too! :D
From what I've heard it sounds like the fish are spotty on the banks but they're getting more plentiful. This should be a good weekend if the weather settles down...
Best of luck!
