The Sustainable Presidio Park

How do we make the Presidio a sustainable national park? What does sustainability mean? Why couldn't the Army sustain a base here in perpetuity?

We may ask more questions than we answer on this level, two-mile walk around the heart of the Presidio, but we'll sure have fun!

Meet Ranger James Osborne and special guests at the temporary Visitor Center, 105 Montgomery St. at Lincoln Boulevard.
