I wanna do these. Well we wanted to build natural habitat exhibits for one thing. And we did do one mode exhibit, an elephant exhibit. And the mode was actually the natural ground water because we were only a few feet above sea level there in Crandon Park Zoo. And it worked out well. We built an elephant night house, that consisted of very, very heavy steel bars spaced so that a person could run between them if you had to get away from an elephant. And they worked out very, very well. It was a very nice exhibit.
