Mad Mat's question as to the legality of an inflatable in the park is quite relevant and had never crossed my mind. I assumed that since U S coast guard wears them and offshore sailors use them it would not be an issue. I have sent an inquiry to the park and will post the results when I get an answer. Mat, if you have saved me eventual grief how do you like your steak? ( or pasta prima vera if your one of those veggie types)
