I went today with my Brother, up from Florida and it wasn't pretty. His nickname is "cold front", we were humbled.
It was my worst excursion to Green and needless to say we won't be watching the game tape of this one!
As far as turnover, Im not sure, I don't think so as the water temp was in the 70s still.
Found plenty of schools of shad in and near structure, they were up flipping at us, but biters were seldom seen.
Wind was tough, crisp.
Tried everything I had, sorry I'm no help!
