Grandfather Mountain was originally privately owned and Mildred came to live there. She has a fabled story and was deeply loved, she had many cubs and lived to be 29 years old. The park refers to it's kept animals as living in wildlife habitats., and the bears have their own pool for refreshing dips.
The wildlife habitats are just that, they are natural land but the animals are kept in by ravines or fencing. It is always sad to see an animal caged in any way, but these bears live forever and the children and adult visitors adore them.
