If you zoom in you can actually see the Invisinet against the sky. The saguaro cactus skeleton in the left of the shot is actually one of the supports for the fence! This whole exhibit complex is simply fantastic.
The two coyotes in this photo were eerily close and the invisinet is a brilliant concept that unfortunately has not caught on in a big way at many other zoos. The entire park is fantastic and I'm sure that I'll re-visit it at some point in my life as I went in 2008 and 2011 and I'm already missing it just by glancing through the photos in the gallery.
