That'll do it. Long time ago we had some property in Ruiodoso NM. Our mail box was on a curve. With out fail each year this first time we went up to ski we found the mailbox had been wiped out and the Postoffice had stopped delivering. So one year Grandpa had me buy a 8" high carbon steel pipe. We rented a backhoe post hole digger and sunk that pipe 11 feet down and filler er with Quickcrete. Then fashioned a mailbox out of 1/4 inch plate steel and welded in on.george wrote:Anygun, i knew you were not serious. But I have considered the scenario about 30" down with the post hole digger in this rocky soil here, replacing the mail box again.
All we had to do after that is paint it when we went up to cover over the paint transfer from cars and pick up the odd sideview mirror and bits of trim that got deposited in front of our mailbox.
