Here is an old structure I found along the roadside in MN. I used PS Content Aware to remove a mailbox and a poster that distracted from the texture of the old wood.
If current legislation is passed (in several states) photos like this maybe in jeopardy. Landscape photographers should be aware of these "farm land protection" measures.
Basically, they say that photos of "farm land", or "farming operations" cannot be taken without the owners permission.
Many landscape venues could be off limits if they include any "farm land".
