North v. South
Well, here we go again with talk of a county split. South County has the population and tourism to support the ability to be a county of its own. North County, with a lower population density and much less tourism, would have difficulty standing on its own. Its needs are much more agricultural, and there is no desire for urbanization. It more closely resembles San Luis Obispo County, and if a county split ever did actually materialize, North County should merge with SLO County.
