I am completely relaxed now that I've straightened out my mangled mailbox...... but, now you got me thinking we have snow coming again on Monday. What should I do? He's coming back.
I think the Mr. Plows in Michigan are probably much better than they are around here.
How about setting up a game camera to snap a few shots of him hitting your mailbox? Then you could confront him or his insurance agent about paying for the damage.
