He probably got out to check the damage, saw the big bullet, and thought, "That's Cool. I could use this." Sorry for the loss brother. I think we had a long thread here a few years ago about mailboxes, damage, mailbox baseball, postmasters, carriers, etc.
We put our box up at the new farm according to USPS regs. The carrier wanted it where SHE wanted it. refused to deliver mail until we moved it. Not.
We had it back off the road so the carrier was safely off the road in the blind curve in a cleared gravel pull off. Also kept the wife and kids off the roar when checking the mail, and put the box out of play for mailbox baseball.
Attempt to swing at our box, you catch air hitting the hump of our gravel drive and drop ten feet into the mush of the culvert fed ravine below... You might hit the willow.
We didn't move the box, the postmaster moved the carrier.
