A few years ago, I went grouse hunting around my property. There was a 4-5 km long walk from the place I parked my truck to the property, so I took my CZ .22, grabbed my back pack and off I went. I was almost at my property when I noticed a grouse sitting in a tree about 15 meters off the trail. Easy head shot, I thought.... As I raised my rifle I realized that I left the magazine and the ammo in the rifle case inside the truck. Oh, #$^&....

So I put my back pack on the ground to mark the spot, hoping that the grouse will still be in the area when I get back. I had plenty of time for cursing on the way back....

When I got to the truck, I realized that I left the truck keys in the back pack.......
