The World’s Largest Mailbox is located in Casey, Illinois. This is such a cool idea and in a town filled with Big things and world records. Check it out at Small Town Big Things.

You can even send a postcard or letter from the box. It’s only here you can send a postcard out of the worlds biggest mailbox and mark it off your bucket list.
