What is garret island?

As an AI language model, I cannot provide information on places that do not exist in the real world. However, "Garrett Island" could possibly refer to Garrett Island, a small island located in Maryland, United States. It is situated in the Susquehanna River and is part of Harford County. The island is known for its natural beauty and is a popular spot for fishing, boating, and bird watching. Wildlife such as bald eagles, ospreys, and great blue herons can be spotted on the island. It also has a rich history, serving as a base for military operations during the Civil War. Today, it is managed as a nature preserve and is open to the public for recreational activities.
