Not a good idea. I've driven on that part of the sea shore and it is rough and very rutted. Go to Mustang Island. Port A is right there and the beaches are groomed and maintained by the city. And being that you are new to sailing its nice to have someone near by if things go terribly wrong. There is no one down there. I also saw alot of jelly fish on the Padre N.S.S. Have fun!!
