#2 (Farm/Ranch setting):
* I Leave My Heart in the Dust Where You Walk (http://akintay.livejournal.com/187483.html): Jensen's life is pretty simple: he runs the ranch his parents left him, spends what little time off he has with his best friends, and occasionally drives for miles to hook up with men he will never have to see again. He tells himself he isn't really gay and that he's happy with the life he leads. But then Jared – tall, beautiful and vibrant – arrives on the ranch looking for work, and Jensen begins to question who he is and what he really wants. Featuring: puppies, horses, skinny dipping, mud fights, sex in a hayloft, and meddling best friends.

* The Long Way Home (http://archiveofourown.org/works/264347): Eighteen years old and fresh out of foster care, Jared Padalecki goes looking for answers about who he is and where he came from when he reads his father's name on his birth certificate. But he wasn't expecting to find what was waiting for him... six brothers and a guy he just can't resist.

* Bring Me to Life (recommended for #3 in a different post) in large part takes place on a ranch.
