We leave out snowy winter boots, muddy shoes and umbrellas. Our hallway is pretty wide, some people have welcome mats out and so there is plenty of room to leave those things out sometimes.
Things just don't seem to get stolen here (knock on wood). In a neighboring city they would, but not here. The postman even leaves oversized mail by the door, FedEx and UPS also leave packages. We live in a very secure building in a sleepy little town (Saint Paul, Minnesota).
