On the weekend prior the Pony Swim, "Saltwater Cowboys" begin rounding up about 150 wild ponies that live on Assateague Island.
About 50 ponies from the southern end of Assateague Island are herded into a southern corral. About 100 ponies reside a little further north on the Assateague Island. The northern herd is corralled temporarily before being led down the beach to the main corral.
On Monday, July 25th, 2011, the Saltwater Cowboys moved the ponies down the beach in a light rain. The roundup went well with the ponies making it safely to the southern corral.
