It's also extremely distorted. The monorail section is about 2.5 times the size of the Giants of the Savanna. This map make it look like a tiny area.
It took me a few seconds to work out what was wrong with this map. Is this the first time that Dallas Zoo has put zoo north at the top of the map? Every other time I've seen it, the monorail section is on the left and zoo north is on the right.
