The post office in town is a big busy place. We've changed the shape of its property a lot over the years. When these pictures were taken it had a drive-thru type lot with gates on both sides (alas, as the town became more densely built we couldn't dedicate that much space to it anymore).
Here's our local folks getting ready to make deliveries. They have a lot of local mail in the bin! There's also a separate package delivery service and an air freight company.
