I've only been to Graceland once. It was for my birthday in 1999 and I drove straight there from Chicago with some college friends in an old Civic.
We didn't go for the fancy deluxe tour package but we did get to go inside the house, imagine ourselves rolling around on the floor of the Jungle Room, examined what might have been dings from bullets (!) on Lisa Marie's slide, and paused at Elvis's grave site where we talked about how hot Elvis was (when we weren't forgetting all the possibly dicey stories we'd heard about him).
But seriously - '68 comeback special. Look that shit up. For the man, the music, the leather suit (OMG), and the magic. R.I.P.
