I'm going to do a snowleopard moment, and give an excerpt from my RWPZ review of the North America exhibit.
North America- This exhibit focuses on the variety of life that can be found in North America. The first exhibit is for Harbor Seals. Curiously, their underwater viewing area is set up right in Fabric of Africa, but they technically count as part of North America. Their exhibit is somewhat outdated. Next up is an exhibit for American Bison. It is a decent size and is grassy. Across from these lumbering icons of America is an exhibit for Pronghorn. It is a good size and is quite grassy. This was supposed to be the site of the future Polar Bear exhibit that was canceled. Nearby is a Red Wolf exhibit. The exhibit is a fair size, but has awful viewing opportunities and there is definitely room for improvement. If you up a path from the Pronghorn, there is a very good Bald Eagle exhibit. This sits on the site of the former Polar Bear grotto. While it may have been a small fit for the bears, the two eagles have plenty of room. There is also a nice overlook of the Pronghorn and Bison exhibits from up there, but guests are in the middle of the view.
