Corrected entry: When Taj drives up to the frat house in the beginning, its covered in vines. The flashback shortly after shows the same building with same accumulation of vines. They wouldn't have been that developed or there at all in 1965.
Corrected entry: When Taj first drives up in the golf cart to the house he will be staying at, you can see tire marks in the grass from the golf cart that were made during previous shots being filmed.
Correction: It's a university with hundreds, if not thousands, of students. It's more than possible that some student or faculty member, at some point in the past, could very well have driven a cart previous to Taj arriving in the area.
Correction: It is not a flashback. It is Taj's fantasy of what his father was like in the Fox and the Hounds, which we later find out was a lie. So the building could have the vines in Taj's fantasy.
