Here's an 8mm home movie of Long Beach, California, in 1968, focused on the activity in the San Pedro Bay and Long Beach Harbor. A kind of "Fleet Week" or "Navy Day" also appears to be happening -- which are occasions when the U.S. military interacts with the public and shows off some of its equipment and capabilities. 

Includes shots of the sea from a moving boat, huge Navy battleships, small docked boats, the Long Beach Towers Apartments/International Tower, the Villa Riviera building, palm trees, and other buildings along the shore.
