Virginia's Grayson Highlands State Park is a popular place to camp, but it's also popular for its wild ponies. They were brought to the area years ago to keep some of the vegetation in check, which they did. And they multiplied. Last winter, however, more than half the herd was wiped out by brutal winter weather including heavy snow and sub-zero temperatures. In this short video, learn about the ponies, which, while labeled wild, seems to show little or no fear of humans. You can learn about camping in the park here.
