Now imagine the cute monkeys in the old Los Angeles Zoo which appears to be a public park now. I understand why so much of America is urbanised now. If you leave a place for even a few years the poison ivy takes over. Poison plants! Argh! Run!
Or read about monkeys in the news.
Disclaimer: I like monkeys and I thank BoingBoing for bringing the links above to my attention. Monkeys boing. Boing boing.
