I have lived the same pain. Mine was with an archery deer hunting experience though. I had loaded up my hardside bow case with everything except the arrows and didn't SLAM the tailgate on my truck. When I pulled out of the field and out on the road the tailgate poped open and I lost the world for my bow hunting until I replaced EVERYTHING!!! My bow, release, licenses, knives, extra broadheads, broadhead blades, string wax, flashlight, and who knows what else, gone in a flash.
The worst thing was getting the "STUPID" tattoo removed from my forehead. When I got home and realized what happened I bee-lined it back there but was too late. Some lucky soul got a great package when they picked that up only a few minutes behind me because everything was gone when I went back 20 minutes later.
