Very nice fat healthy flathead. Even though you landed just the one it's the anticipation of landing that monster that in part makes this fishery as great as it is. Full moon or "big moon" definitely seems to be the kiss of death although there are flat heads which will patrol at night during light nights just the odds in my opinion go way down. I'd still rather be waiting for the right run off than sleeping, each of us will get all the sleep we need later on down the road! Great job on the flathead, nice healthy looking fish!
