Sand Dune Riding Places!

[yellow400ex05]

Can someone name some of the places to ride on sand dunes that aren't across the US? I live in NJ. I go to North Carolina in August and i want to know some places where u can ride in the sand. But I don't just want to know about places only in NC.

PLEASE, IF YOU NAME AN AREA PUT THE STATE IT IS LOCATED IN.

Thanks for whoever helps me out!
