🗺 Ahoy there, mateys

🍾📜 Imagine this... You're strolling along the Mackinac Straits shoreline in Michigan, when you stumble upon a message in a bottle. 

You carefully pop open the cork to find fresh paper inside – on it is a message from one of four descendants of longtime lightkeeper George Keller. It offers you a free stay inside the Great Lakes's tallest lighthouse. 

For four lucky people, however, this will be more than a figment of the imagination. The caretakers of the historic Michigan lighthouse recently launched four real messages in bottles into the Great Lakes, as part of the lighthouse's 113th anniversary celebration.  

• The giveaway features various offers for a free stay for one, two, or even up to five people.
