I'll be down on the island from Oct 5th to Oct 13th. I have all the stickers you need for Norton's and Chappy $265 worth
With the Cut open I doubt there is anyway you sneak out there and sweet talk the ranger. When I was there my dad attempted to but was told he would be arrested for trespassing unless he bought a sticker.
I have a spot for the first weekend and the second too. I may live out of my jeep during the 8th, 9th, 10th but may get in on the house for at least one night maybe two. I could help get some guys to the buggie spots if need be.
