Well Ian I think Brent was not even on a slant, as you can see from the picture there is a slight discoluration in the left index of the last pixel on that picture. To the naked eye it seems like he has parked his rig on an embankment but the fact will tell you otherwise.
He tilted the camera about 23 degrees and overexposed the background 110percent. When the picture was downloaded he used photoshop to turn the wheels while moving the other trucks pointing slightly in the other direction. Therefore the conclusion must be that he intent is to cross the body of water, while leaving overworked minds to believe he was merely taking a poser shot...
Jeeezzzz Lemon entry my dear watson...
