Time to invade Canada! I think we can prove that those keys are WMD.
P.S. (Not meant to spark a political conversation)
Same thing happened to me in B.C. last year on my way back from Kamloops with a couple pontoon boats on top of the truck. I woke up to my two labs making quite a noise as a couple kids sprinted away from my vehicle. I was in the hotel room and my dogs were in the canopy of my truck. I'm no macho man but I would still be head hunting if they had gotten off with my dogs.
People have no regard for others property anymore and it really fires me up.
