head around the corner and up to the bridge. Thats where I found 2 yesterday PM, in much the same conditions you describe, outgoing warm water spilling off the mud. Nice spot; I cast at that boat a bit as well as at a bunch of moorings in dark water, but nothing came up.
However; I have to admit I was trying to get to the point that leads out to the Buzzards Bat channel and took the wrong neck. How the heck do you get out to that sand spit :-)?
