It’s surprising what you can find at the bottom of Newport Harbor.

Bicycles, toolboxes, traffic cones, even a boat. There’s lots of plastic and things that have fallen off boats—not that boaters are dumping stuff deliberately; they just wind up in the harbor.

On one memorable occasion, a diver found a gun. “We informed the police and they said don’t touch it,” explained boatman Guy Harden. “Two divers stayed there until the police showed up, saying the gun was part of an investigation. We never heard anything about it after that, sorry to say.”
