This super friendly Pit Bull was as bored at the Quaker Steak & Lube TheLube.com bar as I was. Fellow truck driver student Cucumber's sister worked at the one in Fredericksburg. It was obligatory classmate bonding. I hiked out to the toolbox of my pickup in the parking lot, cut off a hank of line and made a chew toy. My cell phone, a Samsung Note II, automagically made this active GIF, a single photo file with many layers, by recognizing a common background.
