I am pleased to share that we have successfully set a trap for those who leave junk mail.
@dsh1705 There's a creek that runs parallel to our road; following the development of the village into a broader suburb, the creek was built over in certain sections, so this is a concrete cover that has been moved to reveal what's underneath. For some reason, the council (I assume) hasn't moved it back or replaced it after checking due to recent floods. A little dangerous!
