Just to play it on the safe side, I would have spark arrestors all set up and ready to go. I would also repack your silencers because they do randomly check decibel levels. If you don't have paddles, I would get some. Most of everything else you would need can be purchased at a store across the street from the dunes. As for getting in, there has been tons of meetings and talk about changing the voucher system to try and accommodate more people. Holiday weekends are very busy, but fun to watch all the crazy people. Best thing you can do is call up there and try to get the low down on the current rules. When are you looking to go? I go up there about once a month.
