From the artist, Robert Brandenburg: ""While the drive out to The Forbidden Zone has become more feasible over the last 20 years, one is always advised to keep an eye out for apes. Horse mounted gorilla patrols are irregular, but their treatment of human prisoners is known to be harsh. Still, most people who have made the trip agree that the unique sights are worth the risk.
Anybody who is at all familiar with the cinema will quickly get the "Planet of the Apes" reference (the original1968 classic...please !)."
