California Counties Redrawn
According to this map Los Angeles and San Bernardino counties would be split into several counties. Trona and Ridgecrest would become part of Inyo. A huge county called Mojave would be formed from the eastern half of San Bernardino and a county of Antelope would be created which would include Lancaster/Palmdale. It makes a lot of sense and although this is an old proposal, it's a good one!
