Nile Crocodiles

@jbnbsn99: A few questions about the Dallas Africa exhibits:
1. How many Nile crocs does this exhibit hold out of curiosity? Is it swarming with crocs like the exhibit at Disney's Animal Kingdom or is Dallas more restrained?
2. Has ridership on the monorail increased appreciably since the "Giants of Africa" opened?
3. Is it true that the Dallas penguins were once part of a Las Vegas show of some kind?

1. 1.2 Niles of large size (up to 14 feet)
2. Overall attendance to the zoo has increased as has the monorail
3. Not a show, but at a casino.
