@DavidBrown I have no idea but here is an excerpt from my 'Snowleopard's 2010 Road Trip' thread:
Maryland Wilderness – The third and final section of the zoo is an 8.5 acre children’s area that is quite pleasant and geared specifically towards children. There are some cute and innovative ideas, such as lilypads across an actual waterway, an underwater river otter tunnel, a giant tree with a slide in it, pop-up tunnels in an enclosure, a cave with plenty of small critters in terrariums, and of course the obligatory farmyard. It seems as if every single zoo that I visit has a red barn, a petting zoo and a bunch of domestic animals in standard farmyard cubicles.
This large kid’s zone is divided up into 7 areas: Bog, Marsh, Stream, Cave, Woodlands, Meadow and Farmyard. For all of the unique ideas in this multi-acre area the main flaw is the lack of animals. The walk-through aviary has a few species of waterfowl, but we had to search high and low just to find a handful of ducks. The beautiful river otter exhibit unveiled no otters, and the snapping turtle and red fox were also nowhere to be seen in their enclosures. There are plenty of invertebrates, bats, reptiles and amphibians in small tanks, but no showcase animal other than perhaps the otters.
