Carry some meat tenderizer for jellyfish. Coyotes may be a problem on some of the more uninhabited areas. Texas coast is pretty desolate place in lower Texas area. And mosquito's will eat you ALIVE. They were real bad at TCC in Palacious (sp). If it were me I would put in double shrouds and some extra piece of line of a forestay. Demasting would be bad. I raced old ruff Riders down the ditch and thee is not a lot there for miles. Cell phone and VHF would be a good idea. Be safe, rather than sorry. And watch out for barges. They don't get out of your way.
