If you are at all interested in photography, you might want to try out a workshop. I went on one to Death Valley last year with Steve Kossack. He knows the area like the back of his hand and runs a great workshop. You get up before dawn to shoot the sunrise, take it easy during the afternoon and then stay up past sunset.
Here is a page describing the upcoming workshop March 4-8. I'm actually in the first picture on that page (second from the left). If you end up doing it, let Steve know I sent you!
