Is this a permanent structure? It looks like a big tent, but it is hard to tell if the walls are permanent structures from the photos.
@DavidBrown Yes, it's both a large tent and a permanent structure. The Children's Zoo has this tent that is supported by what are likely metal railings all the way around. I know that domestic goats can be fed here and everything in the Point Defiance Zoo's Kids' Zone is geared primarily towards younger children.
