Here's why:

* Temperate Deciduous Forests: Maine is known for its vast forests dominated by deciduous trees like maple, oak, and birch.

* Saltwater on 3 Sides: Maine is bordered by the Atlantic Ocean to the east, the Gulf of Maine to the south, and the Bay of Fundy to the north.

While other states like Oregon and Washington have similar features, Maine is the only one where you can find the specific combination of a temperate deciduous forest surrounded by saltwater on three sides.
