Kelda, I didn't see that scene in the movie, and I don't know if it's even genuine or not.
I enjoyed the movie, but, dang it all, Brokeback has spoiled Jake movies for me forever, it seems!! When the movie started, Jake was selling electronic equipment, and I saw him selling combines and such. Then later, when he embraced Anne, crouched in misery, I saw the ending of the lake scene. It was the same thing throughout the movie...I kept seeing parallels to Brokeback!
