This is one of the two original yards on the north side of the building. The two newer yards, which are the main exhibits, are on the east side. There was a huge line for those (because of a baby), so I did not bother. But the old exhibits each had one adult and there was no line, so I walked through. The left one, seen here, is fenced off but you can just see over the top of the fence (if you are over 6 feet tall like I am). The other one is open for regular viewing, but not all the time. If the gate is open, go there for no wait (I don't think most people know about it).
