Ok, so if you look closely at the photo, at the top of the window inside, you will see what looks like Christmas lights or something.
It is those 5 hour energy drink bottles! Not only where they lined up on the drivers side, but also the passengers side. I stopped at a gas station to get a coke and saw this. What is ironic here is that the two guys inside the truck were asleep. Looks like they needed a refresher of the 5 hour enery drink!
