For the 100th year, people gathered from all over the world on Chincoteague to see the famous Chincoteague ponies make the swim across the Assateague Channel. Seen here from Chopper 16, there's little mystery as to why the fascinating tradition draws both locals and visitors in the thousands every year. Congratulations to the Saltwater Cowboys and the Chincoteague Ponies on their milestone 100th Annual Pony Swim. Enjoy the centennial celebration! #chincoteagueponyswim #100thponyswim #ponyswim #1

Watch the 94th annual Chincoteague Pony Swim in Virginia. The ponies swim across the Assateague Channel to Chincoteague Island where some of them are auctioned off to help maintain the size of the herd and raise money for the Chincoteague Volunteer Fire Company. | KDKA-TV | CBS Pittsburgh
