This Saturday, September 27th, is National Public Lands Day. The event began in 1994 with the basic concept of taking a day to care for shared land. It is the nation's largest hands-on volunteer effort, focused on improving the public lands that North Americans enjoy.
In addition to opportunities for you to volunteer to help improve public lands, the National Park system is waiving all entry fees to honor the country's newest citizens and encourage people to explore public lands.
