One of New Hampshire’s most unique resources is not found on a majestic mountain top… or in the state’s many lakes, rivers, and streams… or even within its forests. It’s actually located on a quiet road on the outskirts of Portsmouth, just waiting to be discovered by anyone who values New Hampshire’s woodlands and natural resources.
