Bay Area national parks group marks 40 years of transformations

"The 40th anniversary is such an opportunity to celebrate four decades of park transformation and what is the possibility for the future," said [Parks Conservancy CEO Chris] Lehnertz, 60, while speaking with the B.A.R. in the community garden at Fort Mason behind the building that houses the Parks Conservancy offices. "It is part celebration of the past and a vision for the future. It is not just a birthday party."
