I understand the issue and appreciate the proactive stance.

For background, I a 40 year resident of California and have lived, worked and/or performed volunteer work in five of the “six Californias”. At present I live in Orange County (part of the Six California’s “South California” and perform volunteer work, including map generation, for an area where the boundary between Ventura County and Kern County (“West California” and “Central California”) runs through the middle of the parking area.

My guess is the only split that the majority in the state would instantly recognize would be “Northern California” and “Southern California”. However exactly where that split occurs is likely to be contested. :)

Were I to hazard a guess, I would start on the coast somewhere around San Luis Obispo and end up on the Nevada border far enough north to include the Mammoth Mountain and June Lake resort areas in Southern California. I haven’t a clue where the line ought to go through the San Joaquin Valley though.

Cheers!
