This summer I am packing my Subaru and headed to the beach with my girlfriend, I just don't know which one as of yet. I feel like I may end back up in Hampton, NH. It's great there and the beach is a good stretch. The only downside I see is that you need to get there early. But I am looking for dunes too. I've heard of some in the south you can drive on. Cape Cod has that too, but I believe it's for off road vehicles, not street legal vehicles like my Subaru. Stay tuned to see what happens this summer.
