The Mt. Lassen Motor Transit Company, located in Red Bluff, has been in operation for over 100 years. When Lassen Volcanic National Park was established, it coincided with the construction of State Highway 36. This placed the company in advantage to provide trips to Lassen Park, since the southern portion of the park was easily accessible. Whether they used Packards, I do not know.
Pumpkin Center is one of those great mysteries to me. For those not familiar It is a small district just southeast of Bieber. I have had asked a lot of knowledgeable people of Big Valley and it seems as no one knows.
Herlong High yearbooks do exist and the school maintains a collection. As to the the murder of Hiram Patridge and Sylvester Coburn at Deep Hole Station, in the Smoke Creek Desert will appear as a separate post.
Thank you for the responses!
