Whatever it is, I'm sure it was being either winched or towed out by that larger vheicle that was on the shore. This didn't drive out on its own. The video quality is poor and far enough away that you simply aren't seeing the tow strap.
I almost shut it off at 1:00 since nothing was happening. btw, the guy with the camera needs his arms put in a cast and 3 valiums shoved down his throat so he can keep his arms steady.
