One thing I wish I knew more about is fire protection. You have city fire departments, county departments, and special fire protection districts. But then you also have CalOES (or whatever it's called now)and CALFIRE (which I thought were somewhat redundant), and with CALFIRE, it seems that sometimes they supply apparatus, or personnel, or sometimes completely run fire services for a district. San Luis Obispo County brands its fire stations with both the county name and CALFIRE. Kind of longwinded.
