The weather is going to suck tomorrow. We were supposed to go to the show tomorrow. My wife has a party on Sunday, so if we don't go tomorrow, we probably won't make it this year. It's always a good time. Since I work with the DOT and NYS on the traffic coordination, I usually park very close to the entrance. Last year I parked right in the circle behind the bus stops on the grass.
It is definitely worth going. I think you can bring coolers with food and drinks and I would recommend it as everything is usually expensive. We are always under the Bethpage Credit Union tent and they supply free food and drinks for the duration of the show, but if we didn't get all the perks, I would definitely not go every year.
Tonight I am attending a dinner with all the bigwigs and pilots at the Cradle of Aviation Museum. If I hear anything regarding tomorrow's schedule, I will post it up tonight. With those high winds and rain, they may trim the show down tomorrow.
If I were to guess right now, I would say Sunday would be the better of the two. Get there early! The lots fill up quick and the roads start backing up. You'll start seeing everyone just pulling over on Ocean Parkway and sitting by their cars. You don't want to do that.
If you just want to fish, maybe head down to RM.
