Sir, usually as little as I can manage. House keys (including John Wayne can opener and small Swiss Army knife), cell phone, cigarettes and lighter. I only add my wallet if I'm leaving the house.

Beyond that, it depends on what I'm doing: poo bags when walking the dogs, flashlight if it's dark, etc.

Hope this helps, and Semper Fi.

Ron H.
