The door on my mailbox rusted off years ago. And because the mailbox itself is encased in a brick structure that looks a little like a gnome house, neither the door nor the entire mailbox can be replaced without significant destruction. Without a door, it has long been an inviting locale for birds, spiders and the occasional lizard and I suspect that more than one rural mail carrier has been accosted, as have I, by a winged, multi-legged or scaled creature.
