These are the hills again.  In fact, the next two pictures are the same thing.

I took this picture because there seemed to be a lot of cacti in one location.  It looked interesting in real life but I don't think the picture captured it all that well.

This is the "perfect" cactus.  Ever since my first visit to Arizona as a kid I've been looking for a Saguaro cactus that has two arms, the same length, and exactly opposite each other.  Up until today I'd never seen one.  I was beginning to think that they just didn't grow that way.  So this was nice.
