That would depend on your definition of 'open range' I suppose.
The San Diego Wild Animal Park fits mine. It sprawls over 1800 acres divided into exhibits that highlight geographic areas rather than individual species. The majority of their animals live in these large exhibits in the same sort of family grouping (herd, flock, etc.) that they would in the wild. The guest sees species such as gazelle, rhino, giraffe as well as many bird species living and interacting together as they would out in the wild. Predator species (obviously) and elephants are kept separate for their safety as well as the safety of the rest of the collection.
It's big enough that the animals don't just live, but thrive. The success of the Park's breeding program is unparalleled. California condors and Arabian oryx are two species that have literally been brought back from the brink of extinction by the Park's effort.
The Park is fenced, the animals well-protected and cared for by a dedicated staff.
Afford? The Park is a major tourist attraction, drawing thousands of visitors a day.
So my answer to your question is: Yes.
