Saint-Gaudens National Historic Site

Saint-Gaudens National Historic Site, the only National Park Service site in the state of New Hampshire, teamed up with the Granite State Clean Cities Coalition to begin transitioning its landscaping equipment to alternative fuels. In 2014, the park replaced one diesel mower with a propane-fueled model and put the new mower to work maintaining multiple cultural landscapes.
