Well, I was coming home last night when my '05 Grizz came through the sliding rear window of my GMC! I had her strapped in som it couldn't slide out, but appearantly it could still jump forward. The good news is that it didn't scratch that pretty new Moose bumper on the front of the Grizz! The irony of the story is that I just returned a Louisiana Guard Dog to Cabela's becuase I didn't think it was all it was cracked up to be (no pun intended.) The Guard Dog would have saved the window though! Oh well. Fifteen years of having wheelers in the back of the truck, and this is the first mishap. Hope it gives you all a good chuckle.
