The zenith city mailbox is comparable to the mailbox in front of the post office, it's the garbage cans that should be smaller. If the garbage cans are smaller, then you have another problem, because the garbage pile from the Monorail event would be several times bigger than the trash can. The scale on this game is messed up big time. Just look at the door sizes on some of the buildings. Can any of the characters fit through those tiny doors without hitting their heads?
