The furnishings are typical of such homes in that period. the ranch was donated to Texas parks by LBJ and remains a working ranch , stocked with bison, white-tailed deer, wild turkey, other native wildlife, and longhorn cattle.
Directly across the Pedernales River from the LBJ State Park is the LBJ Ranch, part of LBJ National Historical Park.
