Iff'n yer plannin' on a "scramble", Pecan Grove would be best 'cause of it's central location to the many lakes and bayous 'round here. State and County parks are kinda/sorta out-o-the-way. I think there's an inside and outside pavillion there. Overnight, weekly and monthly rates. Many (relatively) local crappie fishermen camp there for several months in the spring and fall. Cecil said he gave you the camp phone number. Didja ever call 'em?
Ol' Man River and "Ides of March" are a crapshoot but the earlier the better for larger fish. 24th is the earliest choice.
