Re: fishing in the surf
Yup. 2/0. they'll take all kinds of stuff if they're around- blues, sea trout (specs), jacks, spanish mackeral, ladyfish, etc, especially when they're on the surface chasing bait.
They're a lot of fun to fish, and sometimes can pull fish from far off.
That link I passed on to you with the ebook should have some info on flats and other places to try down there around Galveston.
