Zoológico de Buenos Aires
Feed the animals.I will admit that I haven't been to the zoo in the United States since I was a kid--I don't think the one in Central Park counts--but somehow it's always a draw overseas. And after a few zoo visits in South America, I'm going to venture to say regulations are different. Animals are close enough for you to whisper in an emu's ear. Peacocks freely cross the same paths as visitors. Wombats hang out in grassy patches between exhibits. And one cart sells food for both humans and wildlife. If you have kids or dreamt of being a zookeeper, stop by. Children under age 12 are free. Just be sure to watch them, because I wouldn't be surprised if they tried to smuggle out a new pet.
