Grandson and I delivered a pickup load of srcap iron out to Ben Lomond for the club to use for general things. We were unloading it where we were told to, and my 1911 kept pulling my pants down, so I pulled it out and set it on the truck bumper. Silverado with a flat-top, rubber-covered bumper.
We got done, and I drove all over that place showing the boy the different ranges and a general tour, probably did at least a mile of bumpy dirt roads and trails before I remembered my pistol on the bumper. My face turned sheet-white and I immediately stopped, jumped out, and there it was....still on the bumper, covered with dust and clinging on for dear life, and probably cussing my dumbass and talking about my mama.
So, it ain't hard to do, but there's still no excuse for it.
No telling how many times I've driven off with a coffee mug on top of the vehicle. Always remember it when it bounces off the hood when I stop and breaks in the street.
