That's a great question, LSOC. I would guess at this point he is cruising down Iowa Blvd. with a bunch of empty Listerines rattling around in the back, and now that he's out of mouthwash to chug he's opening a bottle of Robatussin and doing beer bongs with it. Oops, slammed another parked car. And Sizemore drives on anyway, heading due south through the night so he can say that he "went through to Texas, yeeeeah Texas, and [he] had some fun."
It's sad.
