That's neat. I searched for Chincoteague, VA and it's zoomed out far enough you can see "The hook" of Assageague Island. You can watch how the hook has grown over the years. I'd imagine a lot of coastal barrier island areas are like this. Probably could find some areas where small islands appear, move and/or disappear in the time frame available.
Why do we drive on a parkway and park on a driveway?
