Booze
There was an awful lot of booze in this movie. At pretty much every house he stopped. Don't recall any at the public pool, but that scene featured a character who owned a bar where Ned was frequent customer. Was that one of the secondary messages of the film? that the American Dream yields miserable, booze-swigging, borderline alcoholics?
There was also a horse theme going on. Ned pranced with a solitary stallion (stud?) and hurdled show-jumps with Julie ... before coming up lame.
