I used to have a mailbox at my house, but the snow plows kept taking it out, or rather the snow thrown from the plows. I'm on the side that gets the plow first, so I get three quarters of the road's snow thrown up on my side, and three times it's taken my box out, snapping the post. I finally gave up and just rent one at the local post office.
I may try to put it in again, as having a box at home is very handy. Maybe this time figure out a way to fit my box to a 6x6 instead of a 4x4. The hardest part is always digging that concrete blob out of the ground from the prior post.
Gotta love lake effect snow! :)
