Assateague Island
Best known for the "wild" horses who roam the island, the island was almost a developed and populated with full time residents! The Ash Wednesday Storm of 1962 (one of the worst Nor'Easters to ever hit the US) destroyed the development and roads. As a result of this destruction Assateague Island was instead labeled as a National Seashore under the National Park Service - preserving the natural beauty of the island and habitat for animals for generations to come!
