Yeah, I liked seeing just a "normal" old ghost story. Some good insights into Dean's youth, too. Pretty good episode.
I think it kind of sheds more light on why Dean was so irritated of Sam's longing and attempts at having a 'normal life' because Dean had found one as a teen and gave it up (in part because he looked through that window and saw Sam in the car and realized he had to go back for him and didn't want him to become the replacement in his Dad's eyes.)
Of course when I say that I should clarify it explains how Dean reacted prior to season 6. Once Dean went and had his 'normal' life with Lisa & Ben I think he lost the right to be pissed at Sam when he went off to have a normal life with that veternarian.
