The Minnesota Zoo has some amazing exhibits: Russia's Grizzly Coast, Northern Trail and Minnesota Trail are all top-notch habitats that can compete with any other zoo in North America. However, the Discovery Bay building (dolphins, sharks and small aquariums) and the Tropics Trail building are hit-and-miss in terms of exhibit size and realism. I personally believe that it is a top 12 zoo on the continent, but the indoor enclosures are what holds it back from an even higher ranking.
