This happened to me last spring. Had the truck loaded with mine and my buddies fishing stuff for a weekend trip.

Found the truck a few blocks away stripped of the stereo\speakers and all fishing gear among other things.

At least my insurance coverered just about everything - and I got to go shopping for new fishing gear - which was kinda fun I guess...

Now I live in a new neighborhood, but I still find myself grabbing my gun and checking on my vehicles when I hear things going bump in the night...
