If there is a perfect time, I think it is the end of Nautical Twilight as you cross the the heat of a dune into cool, salt air.
Cape Hatteras National Seashore preserves and protects a large portion of the Outer Banks Barrier Islands. This photograph was made at Pea Island National Wildlife Refuge. It was a quiet morning with a flat sea and a hazy sky, a hot August day. In this same place, in April, I have seen 8 foot waves with 35 knot gusts and thousands of Cormorants migrating, as far as I could see in either direction. Hurricanes sometimes cut through these islands. They looked very different 200 years ago and will be greatly changed in the next 200.
