My husband and I went up the night before, camped out... froze our butts off... Then had a blast "tearing" up the beach at the Assateague National Seashore and got kicked off the Maryland side of Assateague. We never knew where one became the other, but we were kindly asked to return to the National side of Assateague . We're "supposed" to ride in the Off-Road-Vehicle zone, but considering how inconsiderate people can be towards horses... We stay away from there. As long as we aren't idiots, the park Rangers don't have a problem with us riding elsewhere.
Fi is quite a bold little mare, but she does find ways (and so do I ) to scare herself.
