There's no natural lakes in the desert. Where were you? Lake Mead?

There are natural lakes. But the man made ones are placed better. They put those where they want them. Have you been to Lake Powell? Unbelievable place. There's a few nice lakes outside of Phoenix too. But I won't be visiting those next weekend.
