This is a great site, but www.texaskayakfisherman.com
is more geared to what you might be looking for.
With that said, I like launching from Galveston Island State Park(by Jamaica Beach Village), or from the South side of the Causeway and fishing the railroad bridge and the shorelines to the east of the railroad bridge.
Good Luck and welcome to Houston. At least you are moving here during the cool season.
