I seriously need to revisit the National Postal Museum, I haven’t been in a long time (maybe 20 years?), and they have some great new exhibits. There is a video there now called All Systems At Work that shows you how mail moves from your mailbox to someone else’s mailbox. The USPS moves hundreds of millions of mail pieces a day and I am fascinated that this insanely high-tech process can happen so quickly!. Check out the video here, or on the 270-degree theater screen at the National Postal Museum. The video is part of a larger exhibit that shows how mail has moved throughout the history of the postal service. You can learn more about the exhibit here.
