Chinquapin Rd out of Matagorda, TX might be a good place to look. My aunt and I use to fish this area back in the seventies when the wind was too high.
If you have 4 wheel beach running, goto Matagorda, TX, out to the jetties and up the barrier island toward Sargent. Check the coves and inlet just over the dunes. Or goto Sargent and up the beach toward Cow Trap and the Cedar Lakes marshes on the barrier island.
