Wild horses, I learned, are part of the experience at Assateague Island National Seashore. This scene while on a summer vacation a few summers ago was just unreal, and totally unexpected. It was fun observing the behavior of the horses near the water. They wanted to cool off, but they did not want to get wet.
I live in South Texas and close by we have South Padre Island, a barrier island in the Gulf of Mexico. It is a beautiful tropical paradise with a lot of wild life, but there are no wild horses roaming the beach. There are companies that provide horseback riding experiences, but to see the horses you have to go find them in the areas where they are contained.
