One of the casinos here has a rain forest, and it also has lions behind plexiglass. Sometimes, a lion will be lying on the overhead of the walkway, and sometimes, they will be on the rocks.
They are always awesome to watch. There is also a dolphin habitat. We have a small zoo here, but the casinos make it almost an afterthought.
At the aquarium in Myrtle Beach, you walked through a plexiglass tunnel with sharks and rays giving you the hungry-fish eye. Lions would be very interesting!
