I read this Fanfic a long time ago and would like to reread it. I can't remember the author or the title but here is what I remember of it:
It is set in the early '90's so J&E are about 50 or so and have never met. Jake is still married to Lureen, but their marriage is stale and unfullfilling, yet they remain friends. They have a granddaughter by Bobby, from whom Jack is somewhat estranged. One day, Jack takes his granddaughter to Walmart for some reason or another and decides to pickup some new reading material for himself. He gets "Close Range" by Annie Proulx. The story BBM deeply distubs him because it is describing him in an alternative life. He is from Lightening Flat, he was 19 yo in 1963, he was going to take that sheep hearding job on Brokeback that summer, but something interfered with that plan and he didn't make the trip. He goes on a quest to find Ennis; does he really exist? I could go on, but does anybody remember this?
