Wow, those are some great shots rubedugan. You have a real talent. You have a good eye for angles in those photos. The pic with the backhoe showing through the door really tells the story.
Great work!
Edit: I love the black and white, and boy the shot with the bright blue sky is nice also. It doesn't look windy the day you were out there, but I bet if it had been you would have been a little nervous inside the structure. That baby looks like she's ready to crash with just a suggestion.
