Thursday, November 12: Salvage Warehouse
Did you know that the Presidio has its own Salvage Warehouse? This month the Presidio Sustainability Stewards will get an exclusive behind-the-scenes look at the "Salvage Museum!" You can help us sort salvaged furniture and knick-knacks while learning about how some garbage becomes artifacts by a special guest from the Trust's own Archaeaology Department.
