Hi Jim,
Do you know the story about Trabuco Canyon and other nearby trabuco landmarks? Apparently, some poor grunt of a soldier in the Portola expedition lost his blunderbuss around Trabuco Creek, and they not only named Trabuco Canyon and Trabuco Mesa after the incident.
Ouch. Lesson is, don't lose your piece when on an expedition of discovery.
The story
Blunder on!
