Thats the way I have been getting them this year here off of the bank. Grass edges, drop offs are better, when the water starts moving, both tides.
Around the Sebastian Inlet in FL we used to pound the shore line with a Chartreuse jigs, rootbeer with red flake grub, tipped with shrimp, at dead high or low tide, and would nail em, after that they would start moving and were tough to catch then.
I haven't tried that in Texas since I'm shore bound, so don't know if it will work here or not.
