Expired Cactus

[my*]

I saw this one night and thought it would be a cool picture. It was to dark so I came back to it another day. When I saw it the second time it was not as great as the first and I got there about 30 min later than I should have. The sun was just hitting the top when I started shooting. I ended up taking 150 photos. Every second the sky changed and it made it look different to me. I can't decide if I like these or not. Here are a couple. If you wouldn't mind looking at my album and tell me what you think of the others.
