This is such sad news. We've camped at Hunting Island every summer for six years now, definitely one of our absolute favorites! The waterfront sites have changed quite a bit in just the past six years from normal erosion and I always worried about what damage a major hurricane might inflict. When Matthew first started heading up the east coast, I had a really bad feeling about things and sure enough, Hunting Island got hit hard.
I'm sure they will rebuild, but it'll never be the same. On the other hand, we have spoken to other campers that have been going for 30+ years and they speak of incredible change over the decades - entire loops for example that are now long gone. I guess on a barrier island, the only constant is change.
We got our phone call last week informing us that our summer 2017 reservation has been cancelled. I'm just hopeful that we can return in 2018. For now, at least we have awesome memories.
This was our August 2016 trip:
