This photo showcases what is a great part of the new building...overhead ropes for mammals and birds to access. One downside is that on busy days I bet that this structure's pathways will seem too narrow and thus crowded but that is the case at just about every zoo.
@snowleopard Yeah it got pretty clogged up here when the building first opened, however the path creates a circle so there are ways around the building if this path is blocked off.
