What is it with these bloody barns?

Not quite sure what it is about old barns, but I can't help but want to take pictures of them.

Distressed white timbers contrasted against the lush green Nebraskan grass. 

Yet more contrast.

Not sure what this barn used to be used for but I like the message.

An old truck I came across on my way to Springfield.

I've driven past this crane many times on my way to Kansas.

Back to an old favourite I've photographed before.
