As they approached the San Francisco Bay and the water gained in salinity, Humphrey became visibly excited and began sounding (diving deeply) to everyone’s delight and amazement. The air was filled with helicopters, and the river banks were lined with thousands of spectators all cheering Humphrey on to freedom. Though the crew lost sight of him that night, they picked him back up in the morning and led him out through the Golden Gate bridge, to the freedom of the Pacific Ocean November 4, 1985, at 4:36 p.m., where he promptly headed South to parts unknown.
