Our neighbor had this out in their barn, and since they didn't want it they gave it to us.
Here are the before and after pictures of the restoration I did.
All of the wood part are new except the wood slats on the barrels, those I just cleaned up and sanded.

I removed most of the rust using this instructables tutorial: http://www.instructables.com/id/Electrolytic-Rust-Removal-aka-Magic/

The area around here is very dry, so a lot of it is just sage brush. In the spring these flowers bloom.
