I live minutes from El Cap State Beach and would say that is your best bet. Refugio is good too. There are a ton of beaches out here that don't get fished often, you just gotta do some beach walking. If you have a kayak or small beach launchable, bring it. Gulp sandworms, live sandcrabs, small grubs and plastics are best for BSP. As for the butts, your better bet is El Cap.
