I collect most of California's Redwood Empire , Humboldt & Mendocino counties, including the RPOs that ran through them. Any town or city I mention is located in one or the other. My primary sources are California Town Postmarks 1850 - 1935 compiled by John H. Williams & the Western Cover Society Mobil Post Office Society RPO Catalog, MPOS U. S. Route and Station Agent Catalog, and the MPOS RPO Directory and AGT Directory California Postmaster Compensation compiled by Alan H. Patera
