Just outside my gate there are three mailboxes on a plank/posts platform. Across the narrow lane, the old farmhouse there has been prettied up to become an AirB&B. I just checked, its a little over $3,000 for five nights.
Guests over there must be city folks driving airport rentals. The mail platform's posts have been backed into so many times - not even in the dark - that they are now leaning back 20-30 degrees. I gave up trying to keep the posts plumb and just maintain the mailboxes securely attached to the assembly.
